Sigh. The Firefoxians must really, really hate me. Not only did the install completely fuck up. They broke "open everything in tabs, not in new windows" again. I absolutely really, really hate this. I've tried the usual settings but nothing works. Could someone please remind me what secret hack I'm forgetting when I want nothing at all to open any new stinking windows, except my own personal self going to the file menu and asking "Open a new window".
Found it.

Dansk fortsættelse: Oversætterne af Firefox er helt sikker velmenende, men for helvede for nogen kedelige, dårligt skrivende geeks. På engelsk står der mundret "Tabbed browsing" i settings. På dansk står der "Fanebladsbaseret internetsurfing". Det hjælper jo ikke at applikationen er oversat til dansk når det sprog den er oversat til er fuldstændig rædselsfuldt. Det er dårlig, dårlig "Jusabilligti".
