My computer system slows down noticeably after starting Firefox 3.6.6, so I would like to shift back to the 3.5 version. What website in the Internet do I go to get the installer file?

I don't suggest downgrading

Your plugins list shows outdated plugin(s) with known security and stability risks.

  1. Shockwave Flash 10.0 r45

Update the Flash plugin to the latest version. See http://www.adobe.com/software/flash/about/


You can try if it works if you disable OOPP (Out-Of-Process-Plugins). See http://kb.mozillazine.org/Plugin-container_and_out-of-process_plugins

You can set the prefs dom.ipc.plugins.enabled.* to false on the about:config page to disable the plugin-container process. dom.ipc.plugins.enabled (currently false by default) dom.ipc.plugins.enabled.npswf32.dll (Flash) dom.ipc.plugins.enabled.npctrl.dll (Silverlight) dom.ipc.plugins.enabled.npqtplugin.dll (QuickTime)

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.


Create a new profile as a test to check if your current profile is causing the problems See [[Basic Troubleshooting|#Make_a_new_profile|Basic Troubleshooting:Make a new profile]] There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files) See http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox


You can find Firefox 3.5.10 here: http://www.mozilla.com/en-US/firefox/all-older.html
