How to uninstall Firefox add-on using javascript?

High memory usage with Firefox?

• Earlier, I had 6 tabs open: http://finance.yahoo.com/news/1-student-debt-crisis-owing-163540505.html http://www.youtube.com/ http://kb.mozillazine.org/Memory_Leak#Virtual_memory https://twitter.com/ http://www.youtube.com/watch?v=E5zWqlcEcAk http://answers.yahoo.com/question/ask;_ylt=Av57SxITnuf0WnD1Abi.Ldzj1KIX;_ylv=3?title=What+would+you+like+to+ask%3F&submit-go=Continue Firefox was using 205,596 K, and that's with all of the add-ons and plugins disabled. Right now, it's at 156,260 K and climbing with only one tab open and no add-ons or plugins. These are the add-ons and plugins that I normally use: Adblock Plus 2.0.3 Adblock Plus Pop-up Addon 0.3 Ant Video Downloader 2.4.6.2 DownloadHelper 4.9.9 Easy Youtube Video Downloader 5.9 Youtube High Definition 1.8 Adobe Acrobat 10.1.2.45 Hulu Desktop 0.9.14.1 Java Deployment Toolkit 6.0.310.5 6.0.310.5 Java(TM) Platform SE 6 U31 6.0.310.5 Microsoft Office 2010 14.0.4761.1000 QuickTime Plug-in 7.7.1 7.7.1.0 Shockwave Flash 11.1.102.63 Silverlight Plug-In 4.1.10111.0 Windows Live Photo Gallery 15.4.3508.1109 Whenever I have everything enabled, firefox can use more than that with only 3 tabs. Could someone disable all their add-ons/plugins, open just those 6 sites, and tell me if 205,596 K is too high? If it is, how much memory is firefox supposed to use? Why is it so high and why does it get higher as time passes? How can I fix it (other than rebooting firefox only to have it start all over again)? I've heard of "memory leaks" which is basically where after you open and close a tab, firefox keeps using that additional memory as if the tab was still open; so if you had 10 tabs open and then closed 9 of them, it would still be using 10 tab's worth of memory. I thought that if I upgraded to the newest version of firefox, "Firefox 11", that the problem would be fixed, but it's the same as it always was. How do you stop memory leaks? I heard about software that accomplishes this by having the additional memory run by something other than the RAM, but is there a way to get it to actually stop using the extra memory instead of just moving it to somewhere else? Is there a way to at least manually free up the memory every time I close a tab? I can't help but wonder if some kind of malware is responsible. What sort of computer problems would cause firefox's memory usage to grow out of control?

• Answer:

  Firefox 11.0, no add-ons, no plug-ins. With all those 6 tabs open, I'm using up about 156MB. You think that's already big? When I enabled my add-ons and extensions Firefox ate up 1.3GB, and I only have this tab open after closing several other tabs! I have the following loaded: AdBlock Plus AutoPager FEBE FoxClocks Free Download Manager iMacros NoScript SelectionSK Test Pilot Tile Tabs Web Mail Ad Blocker Web Mail Notifier WOT Xmarks Adobe Acrobat Google Update Java Platform SE 7 U3 10.3.0.5 MS Office 2010 Shockwave Flash 11.2.202.228 Silverlight Windows Live Photo Gallery 15.4.3535.513 You also have to consider the plugin-container. It's related to Firefox. We have to accept it that FF is a memory hog and doesn't quickly release unused memory. Now I closed FF and came back to this question to answer it, FF memory usage is only about 200-213MB. In most cases, when I watch a video on youtube-like sites it goes up to 1.5GB. That's when I begin experiencing FF becoming non-responsive that I need to click inside the browser to turn the screen blurry white and after a few seconds it comes back to normal view. If I don't click on the browser the it takes a long time to stabilize. I can't say I lack memory as I have 4GB RAM and RAM usage is hardly 2.4GB. CPU is 2-6%. By the way, I noticed that your Java, Flash Player and Win Live Photo Gallery are not up to date. I guess your Windows Live Messenger and Movie Maker 2011 aren't too as they come in one package under Windows Live Essentials. I would also suggest that you get rid of the following redundant add-ons: Ant Video Downloader 2.4.6.2 DownloadHelper 4.9.9 Easy Youtube Video Downloader 5.9 I used to have them too until I discovered that I can just use the Free Download Manager to do all that the 3 can (download files and flash videos). It only uses 10.3MB of RAM and monitors all browsers: http://www.freedownloadmanager.org/
