The crashes refer to JS_Now(), which I think is Firefox asking the system what time it is. Hard to understand why that would cause Firefox to crash.

Some thoughts:

• Have you shut down and restarted Windows Vista since this problem began?

• If applicable: Uninstall BitGuard to fix crashes with Firefox

• As a precaution, try some supplemental scans: Troubleshoot Firefox issues caused by malware.

Hi jscher2000, Thank you for your thoughts however all of them are not applicable to my case. Computer was restarted few times. Browser behaves in this manne under all user profiles. BitGuard recommendation is not my story since I do not have this SW on my laptop. Regaring malware I do not believe that it is my case since no any SW was installed on my laptop for few monthes. Only one recent change I can recall was the update to the latest version of Firefox.

So long story short I am still looking for wise advisory...

I will message you a link for Firefox 27.0, from earlier this month, before the 27.0.1 update.
