I would really like to help you but i don't speak your language apparently. If you can, please add english version or even google translation of your question, so that more people could help you with your problem.

I have my Firefox display version is 8.0 (x86 zh-TW) ~ because said that it would stop my antivirus software avast when update, I cancle the uptade.After that ,my firefox sometimes can't open and no reaction Because the individual is a computer idiot so I do not know how to bring him back. Sorry for my bad English~Thank you for your help.<

Ok, what we know is:

You're from Taiwan, have Firefox 8.0 and Avast installed on Windows 7. And now you have problems with opening Firefox sometimes, probably because of Avast.

Try to do theese things:

1. Update Avast and scan your system

2. If you have problems with Avast - go to http://www.avast.com and download the latest (free) version => uninstall, then install Avast again and scan your system.

3. Check if your system is up to date

4. If you have problems with Firefox go to www.getfirefox.com => download it, uninstall and install Firefox again.

If this doesn't help and Avast won't find any viruses then i don't know what can be the problem. Maybe it's some sort of Windows issue. Or if you can, tell me more details about the problem and we'll think again :)

Oh and select the answer as "solution" only if it really answer your question or fix the problem

Thank you for your help><
