with opera 12x the edit page looks somewhat right. At least better than the one you saw ^^
Assumed it looked the same with firefox 
I don’t have the very latest version of Firefox installed, it’s 23.01 right now.
I cannot terminate this session for now, but in a couple of days I will try it again.
Okay, now I have Firefox 24.0 (latest version)
Still the image upload widget looks scrambled.
Yeah the wiki is still kinda broken, it’s working very limited at most.
