Just do the reverse!
Mine is 0. Why did you set it to 3?
Yesterday, I opened up Firefox and found the scroll bar on the left instead of the right on every page I visit. It's driving me crazy. Does anyone know how to fix it?
IE is working fine!
If there are going to be continuing problems with Firefox, possibly your Firefox profile has become corrupted and it may be better to delete everything Firefox related and start over.
John Wilkinson has given guidelines in the "Forum Sticky" for repairing and/or uninstalling Firefox and how to backup things like Bookmarks. The link is here;
Just a note about that though. If I was doing this, I would first check that I have another type of browser that works, eg IE, so that I can use it to download Firefox again from http://www.mozilla-europe.org/en/firefox/
And finally, after uninstalling I would reboot, (restart), the system before installing Firefox again, just to make sure any registry entries have been cleaned out.
