When I close Firefox, it leaves an open instance each time in Processes. This eats up memory. I've disabled all add-ons, and it still does it.
Over the course of the day, I can have 15-20 instances running in the background and they can range from as low as 3K in memory to upwards of 500000K. This makes my computer super laggy, and I have to go in and manually shut down each one. I've disabled every single add-on and plug in, and tried uninstalling and re-installing Firefox to no avail. I'm at the point where if I can't get this fixed, I'll just have to switch to another browser because this is a huge time suck. If you have any ideas, I'd appreciate it. Thanks.
Use "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: Firefox > Quit Firefox; Linux: Firefox/File > Quit) to close Firefox if you are currently doing that by clicking the close X on the Firefox title bar.
If you use "Clear history when Firefox closes" then try to disable this feature.
*Tools > Options > Privacy > Firefox will: "Use custom settings for history": [] "Clear history when Firefox closes"

please help as the message on the screen reads that the firefox version 3.08 is no longer secure.Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
'''Note:''' You might want to print these steps or view them in another browser.
#Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
#After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
#Delete the Firefox installation folder, which is located in one of these locations, by default:
#*'''Windows:'''
#**C:\Program Files\Mozilla Firefox
#**C:\Program Files (x86)\Mozilla Firefox
#*'''Mac:''' Delete Firefox from the Applications folder.
#*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
#Now, go ahead and reinstall Firefox:
##Double-click the downloaded installation file and go through the steps of the installation wizard.
##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.

When I make my selection it can then proceed to use Firefox. However the next time I open Firefox I get the same problem.
I'm using Windows 7. I have used Firefox for many years with Windows XP and never had this problem. Is there a solution?See [[Firefox is stuck in Safe Mode]]
"Reset all user preferences to Firefox defaults" on the [[Safe mode]] start window.
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. -

You can remove all data stored in Firefox from a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History > Show All History" or "View > Sidebar > History") or via the about:permissions page.
Using "Forget About This Site" will remove all data stored in Firefox from that domain like bookmarks, cookies, passwords, cache, history, and exceptions, so be cautious and if you have a password or other data from that domain that you do not want to lose then make sure to backup this data or make a note.
You can't recover from this 'forget' unless you have a backup of the involved files.
It doesn't have any lasting effect, so if you revisit such a 'forgotten' website then data from that website will be saved once again.
Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

I cannot open emails in Hotmail even though I have disabled all add-ons and plugins.
As of this morning, I cannot open any emails in Hotmail or open any folders therin. I have disabled all of my plugins and add-ons which has made no difference. To the best of my knowledge, no updates have been made to Firefox on my PC since yesterday.
When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.
(1) Bypass Firefox's Cache
Use Ctrl+Shift+r to reload the page fresh from the server.
(You also can clear Firefox's cache completely using:
orange Firefox button ''or'' Tools menu > Options > Advanced
On the Network mini-tab > Cached Web Content : "Clear Now")
(2) Remove your live.com cookies (save any pending work first) using either of these:
* While viewing a page on the site, right-click and choose View Page Info > Security > "View Cookies"
* Alt+t (open the classic Tools menu) > Page Info > Security > "View Cookies"
Then try reloading the page. Does that help? -
I am having this problem for weeks now.
What I tried:
- Defragmentation
- Reinstall Firefox on a different location
- Change download location
- Start Firefox in safe mode and try download
- Disable all add-ons and plug-ins
- Complete malware/spyware scan
- Complete virus scan
- Delete downloads.sqlite in the profile folder
- Uninstall firefox and delete the entire mozilla folder in Roaming location
- Disabling antivirus
Nothing helps! I'm only having this problem in Firefox. Downloading with Chrome for example doesn't give any problems.
How can I resolve this problem? I'm really desperate.
Thank you in advance!
YancoThanks for your input but I already said that I deleted downloads.sqlite.

I already tried uninstalling all add ons and then reinstall them again. Can the problem be related to the Siphon add on (which I no longer use)?
You posted your troubleshooting information in another thread ([[/questions/907656]]) that seems to indicate that you use or have used that profile folder with a lot of Firefox versions and are overriding the compatibility check (extensions.checkCompatibility.12.0).
You need to use a separate profile for each Firefox version if you want to use multiple Firefox versions.

I have tried disabling all Add-ons.
I've reinstalled FireFox 6 three time.
Slide show pics fail to load.
I have all of the proper Flash and Shockwave type Add-ons.
I just can't resolve the problem.
Yet my browser repeatedly locks upSending a solution that I have already tried is of no help, but I tried them all again, reloading works sometimes, I have seen in the past that others have had this problem also, of pages not completely loading. So I don't see how you can say I am the only one. When I first started using Firefox it worked great but now it doesn't, one of the updates caused this problem. I guess it's back to IE as it works fine now.

I am having issues with firefox timing out on some secured websites. When I use safari, I have no issues. I am hoping that I can just disable the add-ons and then re-enable one by one to resolve. I need a walkthrough for the disable process however.
Hi usbank1,
I think you are looking for [[Safe Mode]]. All you have to do is hold down the ''Option'' key while Firefox is starting.
Your on the right track for finding your issue. That is exactly the approach I would take!
Hopefully this helps! -

I bought a new computer. I installed Firefox 7.0 then updated to 8.0. When I was finished with Firefox, I closed it. Later when I attempted to open it I was greeted with the message Firefox is already running. It suggested I restart the computer. I did so and continued to receive the same message. Surely, shutting the computer off should close Firefox. I have to use Internet Explorer to contact you.
Sounds like Firefox is "hanging at exit". That problem is frequently caused by an Extension or a Plugin. Read all of the following articles.<br /><br />

I don't know what other details I can give you. I am not very computer wise. Just an every day web browser and emailer. This is a catch 22 problem. For example when I am installing a program; adobe flash player for example, it tells me to close firefox to continue and when I do I get the firefox is still running message even though there is no window. And so the installation isn't completed. I like firefox but this is a bit of a dealbreaker. hope you can help.
* Try this.
* Type in the address bar about:config.
* Accept the warning.
* In the page that appears, in the Filter box, type network.http.max-connections.
* Change the value to 32 (which is probably set to 256 in your case).
* Close the about:config page.
* Restart the browser. -
The game I am trying to play is on Facebook. The internet and other sites work as normal, but when I load a flash game the game begins for about 30 seconds and then freezes and firefox shuts down. I have used INTERNET EXPLORER and the games loads fine. This issue is with firefox plugins, extensions, add-ons...or whatever. I don't know what to do to get this to work properly.
Thank you so much, for once in my computer life I knew what the problem was, what caused it, why it was caused, what it did, what it made it do and most importantly how to fix it and to do it correctly and expeditiously. I can not Thank You all enough for all of the help! I also have Pogo mailed this to all on my friends list, where they have all learned as I have and have fixed theirs also. and the message is being spread. Thank You again, I just can not say it enough.

I have tried setting my homepage to Google and to Bing but Firefox closes as soon as the page loads. Starting it a second time works with no problems.
Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.
*https://support.mozilla.org/kb/Safe+Mode
*https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes
You can try to reset Firefox.
*https://support.mozilla.org/kb/reset-firefox-easily-fix-most-problems
Reset creates a new profile and tries to import some settings from the old profile leaving the old profile intact.
*https://support.mozilla.org/kb/Recovering+important+data+from+an+old+profile
Also check the settings in your security software.
A possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

How do I disable all add-ons so add-on pop-ups do not occur in Firefox?
When I am using an web-based application in firefox, I keep getting pop-up windows for add-ons to firefox. How can I stop these from occuring if I do not want any add-ons ever?

You can access the add-on manager by going into Tools > Add-ons. It's the Extensions tab you want, most likely, since plugins and themes tend not to make popups appear.
If you want to disable the automatic update of add-ons, simply go into Tools > Options > Advanced > Updates and untick "Add-ons".
