I've had nothing but trouble with 6.02 Firefox. On my 3 machines, 2 laptops and a desktop if I leave Firefox open, not being used it will lock up - 'non-responsive' after an hour or so. Every time.

From what I have been reading, I think I should ask why firefox 6 is always 'hanging' instead of crashing. Thanks for your help

So there aren't any crash reports visible on the about:crashes page?

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

I didn't find crash reports on the one laptop I had used previously-maybe it doesn't hang up. But this desktop has tons of crash reports. This computer has Kaspersky and the 2 laptops have AVG which just uses Windows Firewall. When Kaspersky expires, I'm going to change to AVG.

Somewhere I read a report saying the video card needed upgrading to 10.6 on the desktop ATI. I don't how that would apply to built in video on laptops

The one laptop that didn't hangup is XP home whereas the other laptop and desktop are XP Pro.

That looks like a problem with the Mozilla ActiveX plugin:

  • Process Type plugin Version: Filename: npmozax.dll

The Mozilla ActiveX plugin is not compatible with Firefox 2 versions and later and you should remove it.
For instructions on how to remove the Mozilla ActiveX plugin see:

Thanks I'll try that after work although I have had versions 3-5 with no problems.

@cor-el

You might be onto something. The 2 computers with firefox that hangs have the activeX plugin installed. The one laptop with no hanging, didn't have activeX.

On the 2 troublesome machines, I disabled the active x in firefox. I'll remove them later when I have time. Thanks again.
