Firefox 21.0 on OS X 10.8.4 still has a memory leak that occurs with no Add ons, 1 tab and leads to 3GB of memory usage in 10 minutes.

While using Firefox 21.0 on OS X 10.8.4 with 4GB RAM, Firefox memory usage marches up and up until at 3GB (on my iMac) Firefox hangs and is 100% non-responsive and must be killed with Force Quit. It takes 10 minutes to occur.
No Add Ons
One tab

John99,
Unfortunately, the problem was WORSE in FF 22.0. I regressed to FF21.0 and shut off automatic updates. I may even go back to FF3.6, which is the last one where I didn't see this problem.
Thank you for trying but as a longstanding developer I know that pervasive memory leaks is a sign of a broken development process. Thank you for trying...

You installed the "DownLite" trojan, perhaps under a different name. Remove it as follows.

You may be wondering why you didn't get a warning from Gatekeeper about installing software from an unknown developer, as you should have. The reason is that the DownLite developer has a codesigning certificate issued by Apple, which causes Gatekeeper to give the installer a pass. Apple could revoke the certificate, but as of this writing, has not done so, even though it's aware of the problem. This failure of oversight is inexcusable and has compromised both Gatekeeper and the Developer ID program. You can't rely on Gatekeeper alone to protect you from harmful software.

Major issues with a add-on Emoji Cheatsheet and missing add-ons in Firefox 37.0.2 ?

As soon as Firefox updated me to 37.0.2 installed I started having issues with missing add-ons and missing tool bar buttons.
Instead spending all day reloading add-on from "Refreshing" Firefox I just started going through my add-ons and disabling them and restarting (4-5 at a time) till thinks went right. I spent a hour last night till I got down t last few that could because it . I left FIREBUG disable and things started working as is and Compatibility Reporter started working too.
Well I woke up to start Firefox and to my shagrin it was messed up again. So I went back through and and remembered the few last add-ons I re-enabled right before I disabled Firbug. So I disable it and sure enough things went back to normal.
What Add-on was that?
'''Emoji Cheatsheet :: Add-ons for Firefox'''
[https://addons.mozilla.org/en-US/firefox/addon/emoji-cheatsheet/?src=ss]
When the icon for it shows on my toolbar everything else shows, yet when it goes awal many other things malfunction. I tried reloading Firfox several times and nothing change. So when I disable it and restarted things were normal and working.
Anyone else experience this?

Sorry, the post about clearing your cache was meant for a different question.
I suggest opening a ticket on the issue forums for this plugin: https://github.com/johannhof/emoji-helper/issues
P.s. If it helps, I currently have 16 add-ons installed.

How can I check whether new versions of Firefox are compatible with my add-ons? I specifically need to know this regarding Zotero as I would very much hate to loose my reference data base when changing from one version of Firefox to the next ...

Is there an add-on that can help me with this? Or do I just install the new version and hope for the best?

Firefox 9.0.1 is a real old version and is no longer supported - Firefox 24.0 is the current release version.
Open the Add-0ns manager tab and click on '''More''' for each extension that you have installed. Near the bottom of each "More" there should be a link that will take you to the download page where you can verify compatibility.
Or use this extension - https://addons.mozilla.org/en-US/firefox/addon/is-it-compatible/ - but I'm not sure how well it will work when you are so many versions 'behind the curve'.

Firefox crashes regularly with different add-ons

Firefox is crashing with almost any new add-on I install. At first I thought it was a problem with the add-ons, but because it happens so often I suspect it may be something else. I have deleted and changed profiles and I have completely re-installed but I still have the same problem. The most recent add-ons to cause problems have been Zotero and iGoogle Toolbar for Firefox.
I've included a crash report below, but I'm not sure if that report is relevant to this issue it may have been to do with something else.

Hi,
I do have exactly the same problem. Firefox worked fine with all types of Addons. Since then, i upgraded my OS to Snow Leopard, reinstalled FireFox, and reinstalled the different addons. The weird thing is that it lets me install some addons and restard FireFox correctly, but some other addons just crash FireFox at restart.
Addons that gets installed correclty:
- Firebug
- Download StatusBar
- Siphon SyncAddons
Addons that crash firefox at restart:
- ColorZilla
- XMarks
My Flash player version is uptodate by the way. (Version d'Adobe Flash Player 10.1)
Any idea?

I want Firefox to open to my homepage every time after it crashes. I do not want it to return to the tabs and applications that caused the crash. I am willing to lose information. How do I do this?

Firefox crashes or seizes up when there are too many tabs and applications open, and causes my computer to crash or seize up. I use task manager to close Firefox or I restart my computer. Then, when Firefox restarts again, it automatically re-opens all the tabs and applications that caused the computer to seize or crash in first place. This is a waste of my time. I want Firefox to reopen to my homepage even if it crashes. I am willing to lose information to have Firefox reopen to a low-memory homepage. How do I do this?

Set the Integer pref browser.sessionstore.max_resumed_crashes to 0 on the about:config page to get the about:sessionrestore page immediately with the first restart after a crash has occurred or the Task Manager was used to close Firefox.
* http://kb.mozillazine.org/browser.sessionstore.max_resumed_crashes
That will allow you to deselect the tab(s) that you do not want to reopen, but will allow to reopen other tabs.

* http://kb.mozillazine.org/Browser.sessionstore.max_resumed_crashes

* https://wiki.mozilla.org/Session_Restore#Preferences
To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website. 
If you see a warning then you can confirm that you want to access that page. 
*Use the Filter bar at to top of the about:config page to locate a preference more easily.
*Preferences that have been modified show as bold (user set).
*Preferences can be reset to the default via the right-click context menu if they are user set

The firefox doesnt open because it has high memory usage

I use firefox normally but have started seeing issues with the firefox version 3.6.13 and when i reopen the firefox it says " Firefox is already running " when i check the memory usage it is using most of the CPU usage and memory ~ 800 K or even more . I have to kill the firefox using the Taskmanager each time and then open firefox

Safe mode did not help.
I have disabled ALL extensions and plug-ins, but the problem with "zig-zag" memory usage still remains (I've not tried to leave browser open for the night yet).
I think I'll do clean reinstall with completely new empty profile (without sync'ed information) to try this out. If this works, I'll start adding stuff (configuration, sync, features, etc) to see what causes the problem.

How do I go back to my last version of firefox, the new version isnt compatable with my add ons

my add on tabs are not showing up

To downgrade to Firefox 4 first uninstall Firefox 5 beta, but do not select the option to "Remove my Firefox personal data". If you select that option it will delete your bookmarks, passwords and other user data.
You can then install the latest version of Firefox 4 available from http://www.mozilla.com/ - it will automatically use your current bookmarks, passwords etc.

New firefox installed - didn't give me the option of not installing it before telling me that (essential to me) add-ons were incompatible. How can I get the old firefox version back?

I would not have installed the new firefox if I had known in advance that two of my essential add-ons would no longer work. Now I want the old firefox version back so I can continue to function until the add-ons are updated. Suggestion: when you notify user that add-ons are incompatible, give the option of reverting to an earlier firefox version.

Firefox now always stores the old session, and you can access it by going to the History menu and selecting "Restore Previous Session"
If you want Firefox to display the message to save the session, it can be turned back on by changing some preferences.
# Type '''about:config''' into the location bar and press enter
# Accept the warning message that appears, you will be taken to a list of preferences
# Locate the preference '''browser.tabs.warnOnClose''', if its value is set to '''false''', double-click on it to change its value to '''true'''
# Repeat this for these 3 preferences '''browser.warnOnQuit''', '''browser.warnOnRestart''' and '''browser.showQuitWarning'''
If you always open the last set of tabs, an alternative approach is this:
# Click the orange Firefox button, then select options to open the options window
# Go to the General panel
# Change the setting "When Firefox starts" to "Show my windows and tabs from last time"

I updated Firefox and the extensions and keep getting "restart firefox for changes to take effect." Even after restarting, none of the add-ons actually update and do not appear, for instance, noscript. Please help!

There are a bunch of add-ons that recently were updated, including noscript, adblock, etc. These add-ons were updated successfully and say in the add-on window they will be installed the next time Firefox restarts. There's also a bar that says "restart firefox now" and even when clicking restart firefox, none of the updates seem to load. I had to manually download the noscript the last time to get it to work but alas with the latest update, again, same problems. i tried disabling other plugins with no impact either. Anyone else having a similar problem and does anyone know how to get this resolved?

Delete the files extensions.* (extensions.rdf, extensions.cache, extensions.ini, extensions.sqlite) and compatibility.ini in the Firefox [[Profiles|profile folder]] to reset the extensions registry. New files will be created when required.
See "Corrupt extension files": http://kb.mozillazine.org/Unable_to_install_themes_or_extensions
If you see disabled, not compatible, extensions in "Tools > Add-ons > Extensions" then click the "Find Updates" button (in Firefox 4: right-click the extension -> "Find Updates") to do a compatibility check.

IE works, Firefox has no connection- no error message- just continues to say "new tab" and "go to a website," when something is entered, it thinks for a moment, but then nothing happens. Chrome shows error 137 and safari cant find internet.

Firefox and Chrome stopped working for apparently no reason. IE works. Have tried proxys, firewalls, and restarting. NOTHING WORKS. Firefox is the oddest as there are no error messages, but just shows practically no movement. Only movement is a quick "loading spin" in the address bar, but then nothing. The tab continues to read "new tab" and the address bar says whatever site I typed in, but goes no where. Chrome shows error 137 if that helps.

It's not just you, I can't authorise my phone. It seemed to go down just after I started the update (it wasn't my fault though). I am using chrome, and it does not seem to be a firewall issue, or the bannerblock issue that I read about else where, since I dont have that program installed. Strange though how the support forum is still running. If I go to http://www.apple.com/support I get nothing, but googling topics allows me to see em.

Firefox won't close without using Task Manager - end process; can't start in safe mode or disable add-ons

I've been having a memory leak/hanging problem for weeks -- FF slowly increases memory usage until it's at almost 100% and then freezes and I have to shut it down via Task Manager/end process.
Last week I updated to FF 12, and I also added the Web Developer 1.1.9 add-on. Now every time I open Firefox it tries to go to the "Web Developer installed" page, but the page never loads. Nothing else will load either.
I can't start in Safe Mode because of the problem with having to close it in Task Manager. I select "restart with add-ons disabled" and it just never opens. The Add-On manager page won't load, so I can't disable Web Developer to see if that's the problem.
I've uninstalled Firefox and reinstalled, and it still goes right back to the Web Developer page when I open the freshly installed copy.
Help, please!

Have you already tried clearing the browser cache, opening a blank tab, and trying to open some other website ?
* [[how to clear the cache]]
Instead of trying to open safe mode from within the User Interface menu have you tried alternative methods such as holding the shift key when you start Firefox. (After checking for running Firefox processes or plugincontainer and killing them if found )
* see [[safe mode]]
* [[firefox hangs]]
If using safemode does not help first of all try creating and using a new profile.
* [[Basic Troubleshooting#w_8-make-a-new-profile]]_8-make-a-new-profile
If all the above fail then try a clean re-install of Firefox

Firefox 26 on OS X 10.9.1 still has huge memory usuage (leak) which leads to crash

Hi, The subject is sort of self explanatory but for the last few months (not sure exactly when) i have had regular Firefox crashes, it seems to happen when i'm out of memory and FF has used all the available RAM.
I have a MBP with i7 and 8gig of RAM using the latest OSX 10.9.1 and latest FF 26. I always keep up to date with the software.
Usually i have about 20 or so tabs open and go back and forth between these. I have googled and read allot on this topic and most people recommend starting in safe mode, without add-ons , creating clean profile etc and i have done these but slowly i get back into the same issue even after a clean profile....
It seems for every FF update the memory usage increases....back in the day FF was extremely fast and efficient. Or maybe latest FF just wants to remember so much and save just to much old information which leads to these ridiculous amount of memory usage, i tend to go over 3-4gig RAM after half a day alone before it crashes and all my tabs are lost which is extremely frustrating. Is there a way to limit the memory usage?
Only helpful tips i have found so far that seems to remove allot of garbage from the cache and the footprint is going to about:memory and run the "minimize memory usage", this has been working great and so far after 2-3 hours its steady on 900meg (more or less) with 16 tabs open.
Isnt this something FF needs to do regularly to get rid of old stuff ? i saw youtube and many other old stuff in the cache which i was not using and caused FF to go over 2 gig or so before i run this so why isnt this automated? as a user i shouldnt need to care about such thins really. I also used Safari for a few weeks with same amount of tabs and it never goes over 800-900 meg.
I really hope you guys can explain and give me some tips as to how to limit the memory usage of FF and not the regular make a clean profile and generic tips. I really think the problem is FF and nothing else. I done extensive testing here and i'm using just a few add-ons
Adblock plus
All in one Gestures
Swedish dictioanary
Downloadhelper
Screengrab
Download Statusbar
Sorry if i sound irritated but having to lose my tabs daily and being forced to bookmark my tabs constantly just in case FF crashes has been bugging me for a while now and i'm on the verge to switch browser but frankly there is no other browser as good as FF (offering same amount of plugins/add-ons) so i badly want to use FF if possible.
If you need any more info let me know.
Cheers

The attachments / gallery seems to have been playing up recently for some reason.
I note that FlashPlayer 12 is now out. When you start testing I guess it would be best to test with that now.

How to stop add-ons manager tab from loading at start up of Firefox 3.6.17 (disabling the update add ons option doesn't stop it)?

Recently firefox has started loading the plugin checker in a new tab everytime it starts. This is annoying and turning off the automatic check for addon updates doesn't stop it.

It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.
Delete the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.
* Help > Troubleshooting Information > Profile Directory: Open Containing Folder
* http://kb.mozillazine.org/Profile_folder_-_Firefox
* http://kb.mozillazine.org/sessionstore.js
If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well. 
Deleting sessionstore.js will cause App Tabs and Tab Groups to get lost, so you will have to create them again (make a note).
See:
* http://kb.mozillazine.org/Session_Restore

Everytime I close and reopen firefox, my themes and add-ons are gone and I need to re-install them.

To be more specific, my chosen custom theme will be deleted, buttons for add-ons such as "white on black" will have to be added again, and settings such as the preference to save downloads on my desktop instead of a "Downloads" folder will be reset to the latter.
Also, when I reopen the browser, I get the Firefox Start Page, as I have specified, but I also get other tabs such as the homepages for greasemonkey and userstyles.org.
Please do help me if you can, I need a solution. I choose a theme that changes the entire skin to black because I work on the PC for long hours, and I need dark colours to help my eyes cope with the stress. It's going to be a massive strain if I have to re-install the theme everytime I close and reopen the browser.

I've tried that, but the problem persists.

Firefox 21.0 on OS X 10.8.4 still has a memory leak that occurs with no Add ons, 1 tab and leads to 3GB of memory usage in 10 minutes.
