firefox 5How does everyone feel about the Firefox 5 update?

What are the pros and cons of updating to Firefox 5?
Tons better than my IE9. I have no complaints and haven't had one since I started using Firefox regularly.

I just wish everyone else wouldn't bow down to the Microsoft bully and configure their sites for Firefox (or even Chrome).
the cons it will always have is that every new version wont be compatible with some add on if you use any.
