My firefox has managed to muck itself up. Its lost all its search options at the top and refuses to add new ones. It also is refusing to add extensions and crashes constantly.

I have tried uninstalling it and reinstalling it but the sam,e thing happens.
So how do i completely uninstall this programme so that i can put an entirly fresh version on?

I don't want my computer to know that it has ever existed! I'm contimplating going back to IE this is annoying me so much.

Uninstall Firefox from Add/Remove Programs.

Use Windows Explorer to confirm the deletion of the installation directory. This is usually 'c:\Program Files\Mozilla Firefox' and if memory serves the uninstaller prompts you to remove this directory completely.

Finally delete the Profiles directory.

Re-install Firefox.

This of course assumes you've backed up any info you wish to keep, like Bookmarks...

Good luck!
