Thank you very much Chris!
I appreciate your help!
No errors are detected during this problem!
I'm playing and after a couple minutes the browser pops out to the desktop with all tabs closing,including the ones not from FOD!The next time I launch this browser it says that
the last session has ended unexpectadly!
I have cleared all cache and temp files,scanned my PC for viruses,but nothing seems to be causing this problem!
I have downloaded Opera browser yesterday!
I have tried playing and it looked better!
I guess it was just Firefox problem!
Thank you all again for your help!
