Before I installed Firefox 5.0 it opened perfectly to my homepage: Yahoo! Mail. Now it will not open as noted above. I went to Google and tried to re-install the toolbar only to be told that it is incompatible with Firefox 5.0.

The GTB 7.1.20110512W version works in Firefox 5.0 by using the Compatibility Reporter extension, I tried it myself due to the large number of postings about the GTB this morning.

As far as that - chrome://tavgp/content/libs/include.js:595 - message, disabled the AVG extension. AVG is going to have to fix the problem with that extension.
