Since I've been using Firefox on my 64-bit Windows machine, every few minutes the browser stops responding, with "Not Responding" in the title bar and the screen fades out for a few seconds. I've Googled this issue and it appears other users are experiencing this too, with some suggestions that it's caused by the Flash plugin. I don't want to disable Flash, 'cause I like to watch videos so can somebody tell me if there's another way to solve this issue?

The flash problem is not only in Firefox, I have noticed after installing flash lagging occures frequently, I only enable falsh when it is needed, I use IE mostly. – Arjang Aug 30 '11 at 22:29

Assuming that you're using the latest version of Firefox (3.6.x), it splits Flash (and other plugins) into a separate process called "plugin-container.exe" that you can see in Task Manager separately from the main firefox.exe process, do you see that using a lot of resources when your Firefox freezes?

If not, then this may not directly be Flash freezing the browser.

(On another note, I have Flash and 32-bit Firefox running happily on 64-bit Windows 7 Enterprise and don't see these freezes)

yeah further investigation across the web is suggesting that this is a deeper problem than Flash. Resource Monitor is reporting that "One or more threads of firefox.exe is waiting to finish network I/O". But with that said, I wonder why this issue seems to manifest itself after I activate Flash. I don't recall trouble like this with IE6 on XP :-) – DaveDev Sep 13 '10 at 22:58

Yes there is. Adobe has got a special website about this problem. You will need to install and use a 32-bit browser to resolve this problem.

I'm already using 32-bit firefox though.. so I don't think this is it – DaveDev Aug 30 '10 at 22:30
so, maybe it isn´t the browser with flash causing the problem after all. Or is the problem gone if you disable flash for testing purposes? – Diskilla Aug 30 '10 at 23:29
