Re: Slow switching between tabs

I figured that its because of cache, i got 1024 reserved place for cache and it was filled with random stuff ( 899 mb ) so it was laggy.. I used CCleaner and now its fine Smiley Happy No extensions or plugins are slowing my FF Smiley Happy

Re: Slow switching between tabs

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.

To Reset Firefox do the following:

  1. Go to Firefox > Help > Troubleshooting Information.
  2. Click the "Reset Firefox" button.
  3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
  4. Firefox will open with all factory defaults applied.


Further information can be found in the Refresh Firefox - reset add-ons and settings article.

Re: Slow switching between tabs

This can be a problem with bookmarks and history not working properly.
Such problems can be caused by a corrupted places.sqlite database file.

You can try to check and repair the places database with this extension:


Start Firefox in Safe Mode 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).
