Firefox 1.0
If you have not install Firefox 1.0, you would be well advised to stay away from it. I recently installed this crappy program and in no tine flat my FrontPage became unstable. This is definitely a Mozilla ( Godzilla type problem). My OS is XP which had no issues, since installing this big talking BS program, I can no longer preview my FrontPage pages in windows explorer. Attempts to uninstall Firefox and recover the functionality have proven futile.

If you have not installed this big talking screw your machine up software, you would be wise to stay away from it.
