Just one small thing... Rated 4 out of 5 stars
Excellent - did what I needed with ease. One small problem at first, I had disabled the menu toolbar, and had to open it up again to get to 'Tools' to launch the add-on. It would help if you could make this add-on accessible via the menu that comes down from the orange Firefox tab. Thanks!This review is for a previous version of the add-on (184.108.40.206.1-signed).
The option to show this add-on in the new app-menu will be available in the next release. (remark: pressing the Alt key will bring up the old toolbar).
