It really is great, but doesn't seem to be working with multi-process on.

Edit: let's hope they don't take too long, edited the rating.

This review is for a previous version of the add-on (1.3.2).

It will be compatible with e10s as soon as bug https://bugzilla.mozilla.org/show_bug.cgi?id=1261585 will be fixed by mozilla.
