I had that problem as well blad. I had to disable a couple of greasemonkey scripts. Googleautopager was one, can't remember the other. Probably anything related to google images will need to be disabled.
Found it! The customizegoogle addon. After turning off greasymonkey it still didn't work so I look around in my addons.
Anyway pretty nice way of browsing images. I just wish there where more options, like go to the original page, copy image ect, but I like how all the images get loaded that works real smooth.
An other Addon I can wait to use is the StupidFilter. They have the algorithms working and Alpha should be released pretty soon. stupidfilter.org[stupidfilter.org]
when I opened FF this morning I noticed a difference. All my youtube links had a yellow background. when I clicked the link this happend:
Youtube videos get embed on the page, I can't describe how awesome this is. At first I thought it was a SU feature but it does this on every site I visit. My only problem is I dunno which plugin does this for me, not grease monkey I turned it off and it still works. Anyone knows?
