Comment 4 for bug 974783

I would like to reopen this bug. Although the fix is helpful, it is not complete. Here are some steps to reproduce:

1. Go to http://mail.google.com/
2. If necessary, log in.
3. Wait for it to load. Favicon is correctly shown.
4. Click any link inside the page (e.g. a mail or a label). Favicon disappears.
5. Wait for it to load. Favion does not return.

The same behavior is seen in http://facebook.com/ . Clicking a link (e.g. Messages, a group, or a person) also makes the favicon disappear.

What the fix did was made the favicon appear in the first time (before that, the favicon was never shown).
