There were a few security bugs in the first 1.0 version and since then Mozilla has come out with a number of updates. Currently, Firefox is at 1.0.4. Try downloading the new one, uninstalling the old and installing the new. You may have to reset some things but it should repair the issue. Normally, if you do a simply uninstall, then reinstall, your Bookmarks and homepage should remain the same. Many folks simply install over the top of the old, but since you're having issues with your current version, it might be helpful to uninstall first. Here's the link:
Hope this helps.
I'm using WinXP Pro SP2, and had switched to Firefox 1.0, which I've been using exclusively for months. Previously, I had been using Netscape 7.2. Last night my Instant Messenger program - Netscape/AOL IM - didn't load and sign on automatically, nor did I have an icon for it on my desktop. When I went to search for it through Netscape, I noticed there was an upgrade available to Netscape 8.0. I downloaded it and installed it, and also upgraded AIM95 (which I thought was my Netscape AOL) to 9.5. So far, no problems. Then, I reopened my Firefox browser, which has the Yahoo Mail Login screen as my home page. I entered my screen name and password, and instead of seeing my Inbox, I was taken to a completely blank yellow screen. (yellow because this is my own personalization for MyYahoo). I can access my Calendar, my Address list, and my Tasks, but not my Inbox or Compose screens. This is completely weird and very upsetting. Even crazier, I can get to my Inbox by using other browsers, but not Firefox.
The only other change I've noticed so far is that I have lost the Sign Out button on EBay, so I cannot log out of my EBay account. This also changed at the same time I lost the Yahoo Inbox. I have had no trouble accessing every other site I've tried.
Rebooting my computer multiple times has had no effect, and Firefox and EBay didn't revert back when I then deleted the Netscape 8.0 upgrade.
Any thoughts? Could this be a Firefox bug, pure coincidence, or what?
