Rated 5 out of 5 stars

Somehow, it interferes with tab session in my SeaMonkey 2.52a1. I had default theme + session, installed LCARStrek, restarted SeaMonkey to apply it, it opened empty SeaMonkey (with this nice theme). Also, about:sessionrestore and History->Recently closed windows were empty (and so was History->Recently closed tabs, which is plain weird). or Another restart didn't bring session back. Switching back to default theme did bring session back. Switching back to LCARStrek brought empty window (without session, again). Switching to Orbit Retro theme brought session back (which is strange-y).

This review is for a previous version of the add-on (2.51).
