I've recently installed FF 3.5, and I'm experiencing the lag problems I've read about elsewhere. Basically, there will be moments when the scroll bar no longer moves smoothly, video streaming gets choppy, etc.
I understand that there is a known problem with 3.5 that the Mozilla people have acknowledged, but I should point out that I had a similar problem when I used FF 3.0, so I can't be sure that my problem is the one they're talking about. Only FF 2.X works well for me. I'm a bit confused with all the info about 3.5 online, so can someone offer some advice? I really don't want to revert to 2.10 again. I tried that a year ago when I had trouble with 3.0, but now 2.10 isn't updated anymore... (Not to mention that it's a bit of a mess to transfer bookmarks from 3 to 2).
Here's some more background that might help:
-I've scanned for malware and viruses, and the results are clean
-I've tested FF with all addons, firewall (Zone Alarm) and antivirus (Avast) disabled, and the problem persists
-I've tried clearing my Internet Explorer cache / history, which seems to be a workaround for some people, but that has no effect
-I don't do anything out of the ordinary when the problems occur (e.g. run some other program or connect some device)
-My system isn't a rocket, but it's fast enough that it shouldn't have this problem. And, in fact, it DOESN'T have problems like this with any other software, including older versions of FF.
