Firefox 3.6.13 hangs freezes repeatedly with multiple tabs open

I am running FF v3.6.13 on a Vista laptop. I typically have over 60 tabs open during a session (pretty much the same ones each time). In the last two weeks, FF has started freezing repeatedly while these tabs are open, whether I am using it or it is sitting idle. I either get a dialog box stating that Firefox is not responding and asking if I want to end it or wait for it to respond, or it simply hangs and I have to kill it via Task Manager.

However, if I run FF with only a few tabs open, it remains running and stable. So, I don't believe it is an extension problem.

Any ideas what is happening?

Hey, M.,

I have had this problem with v3.6.13 and earlier versions, too, but I never was anywhere near 60 tabs! WOwwww!

IMHO, the "issue"is probably caused by your having stretched your virtual memory too far.

My system is XP Pro x86 SP3 with only 2 GB RAM; you must have 4GB or upwards on a 64-bit system, to grow to 60 tabs. Mine gets flaky around 12-15, esp. with a Word doc window or two running as well. Mine used to go troublesome around 8 or so, but I increased my Virtual Memory setting in Windows. You might try increasing the virtual memory setting significantly, if Windows will let you. See if that will help your problem. Good luck!

@ Falling Rock

You seem to have found a plausible answer to the problem.
But at least as I view your post it is breaking the post container, I will repeat your answer and add line breaks in an attempt to make it easier for those like myself to view what you have written; without requiring excessive scrolling.

Thanks very much for the quick reply!

I tried increasing my virtual memory (doubled it in fact), but no joy. Firefox still hangs randomly (and often) when all my tabs are open.

Create a new profile as a test to check if your current profile is causing the problems.

See Basic Troubleshooting: Make a new profile

There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins"

If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)
