Hello! In case anyone is interested: I created a proof of concept - very basic - firefox-qt package and the needed xulrunner package. (No this is no april fools joke) :P You can find more information about the whole affair on my blog: http://friesoft.wordpress.com/2010/04/01/did-anyone-say-firefox-qt-with-archlinux-you-can/ Does anybody know how I can replace the original firefox-qt package on aur? I think it's obsolete and it doesn't seem to work (I think). Best regards, Bernhard Friedreich
