Given that Javascript can cause a browser to crash still or lockup, I wouldn't worry about this unless the tab was on your site. Then it's your code to fix.
Hi I have Mozilla on my laptop, windows 7. In the last couple of days, a tab will crash. This is not all the time and I do not know what to do.
I have Norton Security and it is ok. Please advise.
Thank you for your help.
