I have a stable amd64 system with conservative cflags (for more details see my emerge info below). I have mozilla-firefox as well as mozilla installed. Both browsers work flawlessly in GNOME. Neither browser will start with any sort of reliability in Openbox. Basically here's what happens. In openbox, I start Mozilla Firefox or Mozilla. From time to time (I'm not able to determine exactly what causes this, as there are no errors in the console), the window will start in the correct position and size. From time to time, it will start, but be extremely small (eg. ~75x75 pixels). Sometimes, it doesn't even display (and is not accessible via alt-tab). 'ps' shows it as running.

Upstream is aware of problem and working to resolve it in next release.
