Why is my computer now slower, with Firefox 4, then it was with previous version? It stops and crashes constantly. How can I go back to the previous version?

When I am on Facebook or playing a game, it will freeze and I have to hit control alt delete, to get any response. Within a couple more seconds the same problem occurs. I did not have this problem with the previous version.

Thank you, James.

I tried so hard with FF4 but no deal. It was considerably MUCH slower than 3.6. Every page just had a 2~3 second wait before it loaded up. This was tested on a brand new Windows 7 64-bit install machine too. Flash ran much more cpu intensive as well. I played many flash based games in 3.6 and my cpu usage was never always as it was with FF4 in the 90%-100% range.

I had to get rid of it due to the slowness and the lack of older plugin support: ANYCOLOR which I must run and cannot stand the light colored menu pop ups. Also the buttons in FF4 are worse than 3.6. You can't see them when you have a persona applied.

Staying with 3.6 until 4 speeds up or will give 4.1 a try.

Blood1, yours is more than answer, a question. Maybe you should ask new question for your trouble with FF4.

Thanks for these comments. I could not get FF 4 to open at all. Reinstalled 3.6 (through Chrome) and everything works great now. I advise anyone having problems with 4 to dump it and go back to 3.6.

Does it save your bookmarks?

All my online games, different websites, freeze up my computer, I have to hit control alt delete, to get use back. Other websites are fine. I uploaded new firefox ,2 days ago, never had this problem before. windows 7. I checked for updates of java, acrobat, whatever, no help. I am convinced it is an internal error with the new firefox, and I sure hope they hurry with a fix. I don't want to go back to old version now, just want them to get kinks out of this one.
