Rated 4 out of 5 stars

Great! I don't need to actually visit the gmail site any more.

The size settings don't work exactly right for me. It's consistently bigger. The default settings create a panel that's bigger than my FF window. Set at 50% for both w/h, I get a panel that's about 75% w/h.

This review is for a previous version of the add-on (1.0.4).
