[Tab Mix Plus]I just upgraded to Firefox 20, the back and forward buttons are greyed out and my default homepage won't open.

Posted

Here's what it looks like: http://i.imgur.com/QSefdOQ.png

Also when I open a new window some of the buttons from addons are huge and they don't shrink until I click the download manager button: http://i.imgur.com/AmbB8Y4.png

When the window saying that Firefox 20 had been released came up earlier today, I clicked "Install Later." Later on I was working on something and Firefox suddenly froze. I force-quit it and restarted it and it automatically upgraded to 20, but everything got screwed up like this. Could someone please tell me how to fix it? Thanks.

EDIT: I found that disabling the "Tab Mix Plus" extension fixed these problems.
