I want to intall Mozilla Firefox 4. Will this delete the contents of Firefox 3.6? I was to the point that I was ready to Reboot the Whole system. I called Microsoft and they resolved the Silverstream issue. When in the control panel I click on the delete function all that is does is stay at Blue. It will not delete and it does not give me any message.

The normal method is simply

  • Help -> Check for Updates

on Firefox (Window XP)

You should be able to delete Firefox and remove it, from your Windows XP control panel although that may not be what you intend.

If you have doubts about compatibility stay with Firefox3.6 for now. Some software extensions will currently have problems with firefox 4 (and that iircc may include some versions of silverlight )

Do NOT use any delete settings (or whatever it is worded) that will loose all your passwords and bookmarks.


BTW the safe mode in relation to Firefox is a totally different concept from Windows safe mode, but you probably have no need to use either of them.

On an ordinary upgrade Firefox will preserve your profile details which include bookmarks any passwords.

You should have no problems in installing Firefox 4. You should be able to install firefox 4, and retain any bookmarks etc that were used in firefox 3.6, but sometimes extensions may be incompatible.
