I don't understand this... I'm using Firefox 3 RC1, and for the last couple of weeks, Firefox keeps temporarily freezing randomly. Problem is, Firefox just becomes very very slow and unresponsive for anything up to 60 seconds, to the extent that nothing can be done, and then afterwards it just continues as if nothing had gone wrong.

I've tried: disabling extentions, deleting my browsing history, and even safe mode. None of these made a difference. I'm out of ideas, there's nothing else I can think of! Help?

Reproducible: Always

Steps to Reproduce:
Just normal browser usage.
Actual Results:  
Every so often (up to a few times per hour), Firefox will become very slow and unresponsive (for up to 60 seconds at a time).

Expected Results:  
Acted normally.

Nothing actually crashes so there is no error report to refer to. It can be noted that I have a lot of bookmarks, but this shouldn't affect anything, right?

This is all I've got. There was no "access violation" after it hung so I had to break and get the stacktrace manually. This is what came up:

I have this same problem with firefox 3 now. it is really bad when I try to use my aol mail,  but actually freezes and hangs and is unresponsive no matter where or what I'm doing when I'm on firefox 3. I have actually downloaded other browsers to use because of this problem. When I'm on the other browser I do not have this problem, the only thing is..the other browsers do not have as many features as firefox3 or they just dont let all the features of yahoo mail or aol mail show up so I prefer firefox but if this problem isn't cleared up soon I'm afraid I will have to uninstall it and just use the other browser because it is very aggravating
