Incompatible with SeaMonkey Rated 2 out of 5 stars
Unfortunately, since the 2.0 update, ACR is not compatible with SeaMonkey anymore :(
On a side note, the presence in the add-on bar makes users permanently submit (more or less useless) compatibility reports - even when version compatibility is supplied by the add-on.
