while i’m a big fan firebird, there’s one default behavior i find annoying. if i open a new an url from a bookmark it will automatically spawn a new window; however the preferred behavior for me is to open it in an existing tab. i don’t see any obvious preference to change, but i’m sure there’s some sort of user.js fiddling i can do. any hints? i don’t see anything obvious if i type about:config in the location bar.
