My Reviews

Print preview button (restartless)

The Missing Feature Rated 5 out of 5 stars

Very simple and does exactly what I expect from a Print Preview. I don’t understand why Firefox doesn’t have this built in, but thank you, Guillaume, for filling in the gap.


This is essential for multiple FF installations Rated 5 out of 5 stars

I use a large number of different machines in different sites, and the first thing I do, if they haven't installed it, is download and install Firefox. The next thing I do is use FEBE, together with CLEO, to install the extensions which make FF the comprehensive browser it can be.
Is there a chance of something similar for Thunderbird?

This review is for a previous version of the add-on (5.3).
