Not too sure what you are seeing, is it a blue screen OS crash where XP itself stops working ?

it's a box that opens with blue header firefox.exe- Application error

red circle with white X to left followed by: instruction at 0x1000865c referenced memory at 0x1000865c The memory could not be read. Click OK to terminate program. Click on CANCEL to debug program. CANCEL as well as OK shut down firefox. XP continues to work. Sorry, but I'm not familiar with the tech side of this.

Thanks

I use Firefox on an XP but I do not seem to be familiar with this. Maybe someone else will comment. Possibly a screenshot would help

I just posted the same question. I'm having this problem as well- it started after an update from Mozilla. It's impossible to get around- even in safe mode the same thing happens. Could be a virus?

I will have to leave this for someone else to sort out.

No idea if it will help anyone but I did find
