Rated 5 out of 5 stars

This addon is very useful. It helps me check my gmail, hotmail and yahoo mail, and also automatically login to these services so I don't have to enter password when opening them manually. The preferences are simple and useful too. Works fine on Firefox 3.5.4 and 3.6 beta 1 on both my windows and mac machines.

This review is for a previous version of the add-on (1.5.3).
