Essential Rated 5 out of 5 stars

Essential because it is the only extension that automatically logs in with using Firefox' native password manager.

Just one small request: Please add the toolbar icon in the awesome-bar? (like the bookmark-star). That would be neat.

Rated 5 out of 5 stars

Excellent. The Only feature I miss is to login fully automatically.

This review is for a previous version of the add-on (0.9.3). 

Full automatic login

Although I do not recommend using this feature, there is a hidden setting in Secure Login to enable fully automatic login (without user interaction):
