I have Firefox version 18.0.1 on a PC running XP. I love firefox and it has always been my favourite browser but for the last few months, it keeps freezing on me and then I have to force it closed (end program). After that I cannot restart it (or ant other browser on my PC) unless I restart my computer! This is becoming a real pain - I have done loads of malware and virus scans and nothing has come up. I really don't get what the problem is - any plugins that Firefox detects are not compatible with the current version are disabled, so that can't be the issue. Please help - I don't want to have to stop using Firefox. If it helps, I have noticed this most when I try to log into my bank (with or without other tabs open) - I click log in and it freezes. The last time it happened, I was trying to log into ebay although I don't think it has only ever happened when trying to log in and it certainly doesn't happen to every website I try to log into. Ignore the system info - I wrote this on my tablet while waiting for my computer to load up after the latest FF crash!
