Please advise how to enable hardware acceleration in FireFox 31. All my graphics and other hardware/software is current and updated. I've also paired my Bookmark Toolbar down to under 20 entries.

FireFox is so sluggish that just a few open tabs cause the pausing "wheel of doom" every time I try to enter information or go to another part of the website. Sometimes the pauses are 5-10 seconds, sometimes a minute or more.

I do not have this issue on the other browsers that I use.

Thank you in advance for your help!

Hey, what did help was the Reset Firefox feature. I found the suggestion on this Mozilla thread: https://support.mozilla.org/en-US/questions/1003863

Thanks though for your replies!

I'm not at all sure that this will help.

Start Firefox in Safe Mode 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
  • Do NOT click the Reset button on the Safe Mode start window

You can also check for problems with the sessionstore.js and sessionstore.bak files in the Firefox profile folder that store session data.

Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost and you will have to recreate them (make a note or bookmark them if possible).
