Rated 4 out of 5 stars

I use it a lot for advanced filter and it does it.

I would have liked to know, for cons, how to list urls of a message and then automatically open them in the thunderbird or firefox browser.

I saw that you could use the "javascript with body" option but I do not know javascript ...
Note that I downloaded all my messages locally so I have access to the body.

This review is for a previous version of the add-on (1.3.1).
