You will have to do a complete system recovery as in completely erase the operating system from your hard drive and then reinstall it. A lot of operating systems have this option to where you don't have to go into ms dos mode and do it manually but if the system you have does not offer this then you need the disk that contains the operating system as in windows xp or vista and you have to go into ms dos mode and "f disc" your computer and reinstall the operating system. How did you lose the browser that comes with the operating system in the first place? Maybe you could just perform a system restore and restore your computer to a point before the browser was uninstalled?

Or you could install openSUSE Linux 11.2, which comes with Firefox as the default browser.

Hello kim,

please get me a Firefox crash report ID (a report ID normally starts with bp-) by following the instructions mentioned in the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article.

Thanks in advance!
