After performing upgrade, Firefox 3.6 doesn't go well with Yahoo Toolbar.

When this happened, you can't even use the Firefox anymore.

You have to uninstall Yahoo Toolbar, then uninstall Firefox complete (including all user data) and reinstall Firefox again.

It has to come in a clean sheet;Yahoo toolbar has to be removed totally, otherwise the problem will recur.
