Downloaded new version of Firefox for windows (31.0) Web browsing has slowed to a crawl. It is painful, un-usable. Made no changes to settings, add-ons which ran on 30.0. Speed used be very good. Speed of browsing on Chrome still good and unchanged. Any suggestions?

Poke around safe web sites. Are there any problems?

Then restart.

I think that McAfee Site Advisor is causing this problem. When I disable it, Firefox (31) works at its old fast speed.

Test it for a while. Then decide what to do.

I found an add-on that looks to increase the speed of my Firefox. Still testing, but looks good.

Go to the Mozilla Add-ons Web Page {web link} (There’s a lot of good stuff here) and search for what you want.
