Simple and awesome. However it has a problem with the extension Mozilla Archive Format: the menu item isn't showed rightly. Please fix it. Thanks!

Edit: I use the same versions on Windows XP and Ubuntu 11.04. Both have the problem. Here is how it looks: http://img255.imageshack.us/img255/7097/screenshotmtm.png

This review is for a previous version of the add-on (1.2.2). 

More Tools Menu version 1.2.2 seems to work fine with MAF. I've tested it with Firefox version 7.0.1 and Mozilla Archive Format version 2.0.2 on Windows 7.
Which versions do you use?
