Just solved an ANNOYING problem on my Ubuntu Gutsy installation.

Microsoft Office Communicator Web Access was freezing Firefox 2.0.0.11 right after the login page.
Intensive investigations bring to the conclusion that the Google Toolbar was causing the issue.
After I disabled the Google Toolbar the problem has gone.
Removing the features from the settings didn’t help, only disabling did.

I reported this to Google on their Help forum.

Hope that this can help someone in the same situation as me.

The situation is annoying because:

• if you need Microsoft Office Communicator Web Access, it means that you’re already pissed off because the client is not available for your OS
• your collegues are probably blaming you because you’re not running Windows
• you want to proof that with Linux you can do everything, but then you can’t run a bloody instant message
