firefox takes up WAY too much memory!

175,216
this is how much Ram firefox is using as I start to type this message.
Ok so recently I've been realizing that firefox has been making my computer very very slow. especially when i watch youtube videos they lag horribly! I checked my task manager and firefox was using 800mb of RAM!!! the number seemed to keep rising too! On the Average I have about 10 tabs constantly open.. usually more when there are lots of new topics, but in the end I'm back to about 10.
I tried a test... 2 actually...
my first test is opening all 3 browsers (chrome, firefox, and opera), Open 10 tabs, then simply go to the task manager to check how much RAM each is using. my second test it periodically glancing at the task manager as i type this message.
179,440
that is how much firefox is at now. I have done NOTHING with firefox, I'm typing this message on chrome.. the number seems to rise on it's own! It's like it's storing an infinite cache!
Now let's look at the other browsers... I've let them sit for a while with 10 tabs open...
chrome - 43,620k
opera - 99,312k
firefox - 182,314k
after about an hour or less of browsing firefox usually makes it to 800,000k+. Is this happening for anyone else?
edit: I just had to kill the task because I was checking my myspace and all the sudden it wasn't responding. I check the task manager and im at 100% CPU usage and it's using 600mb ram.

The Memory Leak in FireFox 2 is a well known bug. FireFox 3 does not have that leak.

Unfortunately, the memoryleak is still present in FF3.
I use this tool to free-up RAM, FreeRAM XP Pro:

I hate Firefox. Me and a few buddies of mine on another forum always quarrel and have this debate (I would link to the thread but..). I gave it a fair game and went out to try it. Now i'm forced to use it since i crashed my HD and have to boot Linux. Let me say...it's HORRIBLE.
I liked IE7 way more. FX renders the page horribly. It'll display user avatar instead of showing it, no new posts instead of showing the icon, smiley face html instead of the real face, etc.
As soon as i get my laptop fixed, i'm going back to IE7.
And o yea, IE8 is the worst thing Microsoft has EVER unveiled.

IE8 is still in beta dude. Wait for it to perfect

I know that and personally i wouldn't even call it an Alpha; it's that bad.

In my experience Opera is the best!!
maybe in 1 or 2 years Chrome will be a good one also

I've got to say Opera is the best. I stuck with IE7 for a while, but I got sick of the crashes, so I tried Firefox. I had it set to reload my prev tabs on reopen. Well, Firefox crashed at some point, then when I tried to reopen Firefox, it would crash again because of the saved crash point.
Not to mention Opera has the Speed Dial page along with slide gestures.

lol IE8... it was like the developers were in the middle of typing their code and all the sudden they said File>Save and released it as a beta. Usually beta's have some error, but not too bad, they should atleast be stable. Like someone mentioned above, shouldnt even be considered an alpha.
Opera is great except no spell check, i should google and see if there is a plugin for this.
chome's spell check is horrible. it has probably 500 words total in it's dictionary. Some words it didn't think existed, such as the word familiar, (and i cant remember what the others were). I'm sure in the future this will be fixed.
I like everything about firefox, even the fact that I have downloaded a speed dial for it!
I'm having issues with youtube and firefox, same with chrome. youtube videos only play for about 2 seconds and then stop, also there is no sound. I have to exit and wait for the task to be killed and then try again. anyone else having these problems with youtube? IE and opera dont seem to suffer this problem.

Firefox on *Nix works well The new IE isnt all that bad at memory ive noticed, but then ive never noticed Firefox having an issue either on my work laptop. Maybe you need more ram? 8gb on my dual Xeon tower runs nicely

dude i have 4gb of ram.
and this is what i have open at ALL times.
Photoshop CS3 Extended.
Mozilla Firefox 3
iTunes
and it still runs smooth! :O

I have 1.5 Gb
And I have always open
Opera (At least 6 tabs)
Messenger
Phonostar
Outlook
And I can´t really complain, average response is ok... (Vista included)

Firefox 3 does not have the memory leak present in everything pre-v3 beta 5, so it's something else. I've been using FF3 since the late alphas and the bug was there all the way up to beta 5 when it disappeared and they made dramatic improvements in speed and memory usage.
If you're complaining about RAM usage in a browser these days, perhaps you just need to get more RAM to begin with. I've had Firefox 3 loaded up with 40 tabs of Flash-laden content of all kinds and image galleries with hundreds of pics and barely see 400MB of usage so, I can't imagine why people even bother to complain anymore unless they're stuck with 1 GHz Celeron and 256MB of PC133 RAM...

LOL i was being sarcastic although 4gb isnt too bad seeing as how its your max amount on a true 32 bit OS
I on the otherhand am running a few different flavors on my tower ( Vista is a beast on there but I MUCH prefer leopard ) so the 8GB comes in handy esp when im watching tv on 1 monitor, working with CS3 on the other and have 5-10 tabs open in firefox

if you guys read my first post, you would see firefox takes up significantly more RAM than the other 2 browsers I tried. keeping firefox running for up to an hour uses 800mb of ram!
while opera and chrome manage to stay around 100mb or under, with the same amount of tabs or more!!
also, another thing happened today, I left firefox open and walked away from my computer to play guitar, I played for about 20 minutes, and when I got back it says "not responding" and I checked the task manager and it was at 856mb! I only had one tab open and it was minimized. There is defiantly something wrong, the other browsers dont do this.
IE7 is ok, no memory or compatibility issues, but no spell check and crashes too much.
great news!
i found a spellchecker for opera, I'm gonna try it now!
http://www.opera.com/support/tutorials/opera/spellcheck/

not so great news!
im 7yping this !n opera right now, and aS uuu can see it doesnt even fix my err0rz!!'
It looks like you have to right click and click "spellcheck" and then it searches for spelling mistakes, but that isnt as simple as the red underline to indicate an error.
Firefox still tops spellcheck!

If you read my response you will see I asked what version of FireFox you are running, It really makes quite a difference.
FireFox 3 Is much more leaner on the Memory.

yup I'm using FF3, and I've heard the exact oppisite! I heard that in FF2 there was no memory problem and it appeared in FF3.
the exact version (that says in about) I'm using is 3.0.3.

I never seen something hog so much power when idle. Anyway yeah, FF uses a lot of RAM. You might want to invest in an additional GB

my firefox is only using 85,148k no real awesome computer either, only running on 1gb ram vista pre sp1 and a core2 that runs at 1.6ghz

Opera mobile 11 /w flash

Anyone try the new opera mobile 11. it now supports flash.
If so does it work on stock rooted?
Sent from my GT-I9000M using XDA App

Stock rom doesn't support flash so no. It will now show you the preview image, and if you click through to youtube and press play there it'll play the video in your youtube app.
It also recognizes it's on a tablet, and shows a different interface than the one for the phone.

Personally I love the new opera, I'm using it as my daily web browser. That's saying alot considering how good dolphin HD is.

I've tried Opera Mobile 11, Firefox 4 RC, and various reskinnings of the default browser (Miren, Dolphin, and stock). Opera Mobile 11 seems by far the smoothest, apparently due to hardware acceleration. Scrolling/panning, pinch zooming, etc., are smooth as silk, similar to what you'd see on an iPad. None of the WebKit-based browsers are that smooth, presumably because they don't yet feature hardware acceleration (at least on the NC?). Firefox 4 RC looks okay but doesn't yet have Flash. I think I may make Opera may daily driver for a bit and see how it does with the various sites I visit.
UPDATE: After playing with Opera 11 for a while, I'll go so far as to say that everyone should try the New York Times Web site with Opera 11 in landscape orientation. That, to me, is what tablet browsing is all about! VERY impressive!

Sorry for asking this. Which fingerprint do you use? I can only find Opera mini, but not opera mobile in the market. any pointers would be great.

Download mobile and enjoy
I am loving it......

Opera = no Javascript = pass!

Where did you hear that? Opera Mobile has a very good JavaScript engine.

I've been testing Opera and a few things bug me:
A) Panning up and down the page doesn't "lock" the motion to that axis so that it only moves up/down like every other Android browser does. So the page moves around on BOTH axes (up/down/left/right) and even looks weird as it jitters (or "vibrates") left/right when you only mean to move up/down. In every other browser, when you start panning in one motion, it locks the movement to that axis, which makes for a smoother motion (and rarely do you need to move on both axes, which is why this is implemented).
B) Long pressing on a link doesn't show the URL. Sometimes I'm reading an article and want to see what a link goes to without opening a page. In Opera Mobile, there's no way to do that.
C) I find tab switching to be slower and more tedious than in Dolphin, where the only action needed is a single tap on a tab. Whereas in Opera, you need to tap the (frustratingly small) tabs button, tap the tab you want, and then tap out of it to get rid of the pop-out.
That being said, the re-flow option is much better in Opera than Dolphin. It re-flows the text immediately after zooming, every time. Very helpful.

opera:config, uncheck "Scoll is Pan" in User Prefs, helps a little bit with the vertical scroll lock problem.

The only real issue I've found so far is that it's kind of hard to close a tab. I tap the "X" on the tab but most of the time nothing happens, or if something does happen, there's a LONG delay. Any idea if I'm doing something wrong? I have my LCD density set to 200 so perhaps the UI isn't properly adjusting for that (even though everything looks right cosmetically)?

I had the same issue. Found out tapping the X button twice did the trick. Best browser I've tried.

Just tried that and it works perfectly! Thanks!

Thanks for the tip. This is the best browser yet for the Nook in my view. Quick, accurate (pinching, dragging) and no fuss. I'm running it on a CM7 SD card build and it's fast. Flash works. A question, however: I know Flash works because I use Flash for our site and checked it there. However, going to HBO.com (wanted to grab some Flash video to see what happened) it tells me that my device is not Flash enabled -- so won't let me connect with Flash. ????????????????????

Regarding panning, zooming, etc., I found version 11 to be far worse than 10.1 Beta. Whereas it was iPhone/iPad-like buttery smooth with 10.1 Beta, it's now become choppy with 11 like every other Android browser. I can really tell the difference on graphics-heavy pages like espn or engadget. With 10.1 Beta, panning/zooming on images was silk smooth even while the cpu was busy loading the rest of the page; now with 11, that's not the case.
Ironically though, Web pages load much, much faster (in their entirety) with 11 compared to 10.1 Beta.

OMG, I just installed this a few moments ago... can't believe how fast this thing is! It's as fast as the iPad browser on a rooted. stock Nook. running stock clock speed. Gentlemen, I have found my new browser. End of story.

I don't find it to be as tablet-friendly as the stock HC browser, but it does seem to be very good in terms of performance
Most importantly I can now watch youtube videos on my nook even with HC. Wowza thanks for the tip!

Funny, i am the opposite. For me, this is the first browser in CM7 that lets me view pages like Engadget with good fluidity....

It's also the first I've found that handles xda with any level of fluidity

Same here, I thought I was the only one that noticed. Switched to Opera Mini 10, then back to Dolphin Mini 2 because page rendering more livable, now back to Opera Mobile 11 because of speed, although I still hate how vertical scrolling a pain on long pages.

[APP][UPDATE 2.7.12]FireFox 12 Alpha 1

Im testing firefox11alpha 2
Its fast and very smooth even smoother than stock ICS browser at times
lots of feature like syncing your desktop firefox bookmarks with mobile Device, addons, Flash support
Remember its still alpha not beta but should be beta soon seems really stable so far
also firefox alpha builds are codenamed Aurora in case you get confused with the app name
test youtube desktop view on both browsers firefox was really smooth were stock lagged
Download link
http://ftp.mozilla.org/pub/mozilla....a-android/fennec-12.0a2.en-US.android-arm.apk
if link above goes down or want to check for latest alpha build
https://wiki.mozilla.org/Mobile/Platforms/Android#Download_Aurora
EDIT
updated to 12

It's still horrible for me. Here's why:
I can't get any add-ons to work because they aren't updated...that's to be expected since this is an alpha...but even the ones that are updated, like ab+ aren't installing.
many pages take FOREVER to load, and the ones that do load don't load the whole page.
If I scroll down on a long page, the rest of the page loads, but the top of the page will unload.
Text takes forever to become clear enough to read, and text reflowing takes even longer.
The tab button only works once out of every dozen or so times I press it.
aurora constantly runs in the background unless I freeze the app, and it's killing my ram.
Until every single one of these issues is fixed, I won't even consider using this at all....not even as an alternative. It's really sad to see that the top-dog on PC is so horrible on mobile, because all the potential is there...they just can't understand that most people don't have 80MB extra ram on their android to dedicate to web browsing!!

this is a huge leap in the right direction compared to previous mobile versions
Its alpha so expect things to be ironed out eventually
Everything loads fast and refresh fine for me (im using wifi)
I did noticed it uses almost double resources than stock browser but still its alpha
desktop firefox they significantly drop the ram usage im sure they will do the same with this
also yea one thing i noticed is when page refresh when swiping fast on long pages im sure it will be fixed doesn't really bother me it pretty much refreshes instantly
and yea i noticed it still runs in background and with the resources is uses it could be a problem for some people
I have 185 ram open i just go to recent app and swipe it away it will close

Bump new alpha 12

I don't know why firefox seems destined to suck on mobile devices when it's so good on PC's. Every version I've tried has just been so far behind its mobile counterparts that it's just sad.
Mozilla should take some pointers from the new Chrome beta - I just started using Chrome on my Nexus and it is an amazingly fast and smooth browser that also offers desktop sync.

Perfect for pc. Still trash for mobile.

Does your chrome constantly reload tabs?

Here's an experiment.
If you had a few tabs loaded up in chrome, but you haven't touched your phone in 10-20 minutes, this test is perfect. Load up chrome, does it instantly refresh the first open tab?
On my HTC One thus far, on all roms based off of stock, chrome and chrome beta constantly reload tabs. It drives me insane because at work my wifi is slow.
My N4 never did this. I tested it with my gf's N4 and her chrome caches pages like a pro.
Once the nexus experience HTC One rom drops, I'm all over it, given that that will allow for cached pages.
Btw, do AOSP-built roms avoid the constant reloads?

Likewise: I've got the same thing with CM10.1 and CM10.2: when browsing xda forums with chrome, it continually reloads, but only when I'm logged in to xda. If I logout, it stops reloading. This happens on my Samsung Note 2 and my Barnes & Noble Nook HD+. I haven't tested it on any other platforms.

this is happening in miui on my Note too using Opera, especially on xda on forum theads. one inside a theading reading posts its fine. same if logged in or not.
It is really annoying, only happens at xda for me

Discussion : which browser are you using?

It's mostly a battle between Chrome, Firefox and Opera but, maybe you tried a more obscure browser and it work great for you? I loved the old AOSP browser because it was light on memory and ressources but it's not being maintained anymore and using it pose a security risk. Google Chrome has all the bells and whistle and it support pretty much everything but it's also memory hungry, it eat so much memory that other app in the background are dropped out of your memory to make place for Chrome. It leads us to Firefox, it support less thing but, memory usage is not too bad. Opera is also good.

I've tried quite a few and keep coming back to Firefox.
I don't really have a reason why as I suspect it's a tad slower than most and I see it pretty high on the battery usage on my tablet but it's always just been my "go-to" browser.
I had used Dolphin too for a long time and I can't remember why I stopped. I think it might've been that I didn't like the differences between the tablet and phone interfaces. I am apparently quite fussy.

I may give a try to CAF Chromium browser, it's a Chrome fork compiled with optimization for Qualcomm devices. I'll try it and see if it's better on memory usage. My main complaint with Chrome is that, it eat as much memory as it can, then other apps in the background are forced out of RAM. So, when you want to open other apps, they have to be completely reloaded instead of just restarting them from RAM. Also, I'm fussy too...

Firefox. My beloved (and needed) extensions work on Android. And it's synchronized with my desktop too.

Chromium

Firefox i use linux on laptop so both phone and laptop are coordinated

Been using Dolphin for a couple of years. The main initial reason was the cookies/browsing data clearing is only one swipe and click away when browsing, super handy as I read a newspaper every day which only allows 10 free articles a month lol. Clear data, instantly ready for another 10 articles.

Been a fan of Opera since my first Android phone

Used NoChromo for a while (built in adblocking) but now back to using opera mini or lightning. Use lightning with java script turned off, which makes for a super fast browser. Generally breaks discussion/commenting and some page navigation. But works equally well with java script turned on and is very lightweight.
Find chrome is far too resource hungry and I really don't like the firefox tab interface.

Most of popular like chrome, Firefox, Dolphin are good performer.... Depends upon your needs and usage..... But I am big fan of uc browser and using it for a long time... Better in memory management... Has in built ad blocker.... Its to had limited addons support.... Also has Flash compatability.... Most under rated browser of the store but works like butter for me switching tabs also easiest.... Give it a shot....

Already tried CAF-Chromium, yes it's faster than official Google Chrome but there was still bugs and lags preventing me from using it as a daily driver. Sometimes, web pages get stuck and the app become totally unresponsive and I had to do a force close. For now, I'm back with Opera, not too bloated it's light on memory and it has all the features I need.

Using Firefox because I like the way it works. Interface is, to me, the best of the bunch and all in all it has the best performance. Used Opera a lot but had a lot of excellent | horrible experiences with it. That is, sometimes it was great but often things would not render properly or it would die. Chrome has generally been slower than FF for a couple years now and FF has been much more stable. Chrome blocks much more.
I just want a browser that doesn't make me care about which one I am using. FF is that. It just works.
Also, it gives me more control over crap like webrtc.

I mostly use Opera mini as it loads page faster, it saves data, it consume less memory, and second choice is puffin Web browser it's lighting fast I bet. It supports flash, and had many more advantages.

I always go back to Firefox. I need adblock. I've already accepted annoying ads in apps. So blocking adds in the browser is at least some satisfaction.
