Firefox v. 13.0 was the last version that gave me good performance. I tried 13.0.1 but my speeds dropped substantially. I was able to go back to v 13.0 and resumed my normal speeds. I tried further updates but, since my speeds again dropped, I again went back to v. 13.0. Now, when I installed v. 17.0, not only has my speed dropped, v. 13.0 no longer works, either.
Using www.speedtest.net my ping went from 5 - 8 ms to 85 -135 ms! Right now I get a 113 ms ping using Firefox and a 6 ms ping using Opera. My speeds are showing up the same but the difference in ping times is indicative of the tremendous slowdown I've experienced by doing nothing more than updating to a new release.
I've tried all of the suggestions given to others who have experienced this frustrating slowdown but nothing worked. I finally wiped out everything I've accumulated over the many years I've happily used Firefox except my bookmarks and reinstalled v. 13.0, the last version that worked, but even that failed to solve my problem. What a pain in the butt! I completely removed v. 13.0, deleted all of the folders and installed v. 17.0.
I've run in safe mode, I ran the fresh install of v. 17.0 without installing any add ons or extra plugins. I deleted my profile. I started from zero. Nothing worked.
I can't use Firefox. It's turning my 20 Mbps internet connection into dial-up speeds. Please help!
