[xwiki-users] xwiki issues with Firefox 3

I have seen som problems when using Firefox 3 (beta 5) for linux (Ubuntu), together with xwiki 1.4 (toucan skin): -Tables in e.g. user administration is not showing correctly -When looking at a group page, the scroll bar is missing, so only 15 users are listed -Performance is generally poor. For instance, the top menu bar, and the panels follow the rest of the page when scrolling. This has been verified by a colleague of mine using Firefox 3 RC1, and we see the same performance problems on xwiki.org. Is this something that should be fixed in xwiki, or is it more likely to be a firefox bug? Regards Bjørnar Libæk
