Hi Chri5,

Remember you are using “free beer” not a paid one. You can’t really blame them directly. At least they are working constantly…

Thanks Venkat. Many of the add ons I had on FF4 were not working on FF5. Hope they will have support on FF5 soon.

Thanks very much for this. I was ticked off that I couldn’t add on my Google Toolbar to FF5.
