The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.

To Reset Firefox do the following:

  1. Go to Firefox > Help > Troubleshooting Information.
  2. Click the "Reset Firefox" button.
  3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
  4. Firefox will open with all factory defaults applied.


Further information can be found in the Refresh Firefox - reset add-ons and settings article.

Such issues can also be caused by using as bookmark to go to a specific page.
If you do or did that then try to access the site via the main (home) page and follow the current links to go to the mail page.

You may have to remove the currently used bookmark(s) to go to the mail and try to create a new bookmark (there may be POST data saved with it).
If you keep having problems then you have to stop using a bookmark to go to the mail and use the longer route via the Yahoo! home page.
