Thread:Extension talk:Header Tabs/Performance enhancements/reply (4)

Except for some of the tabs being pushed to the right of a whitespace on a new line depending on a given display's pixel width, they do display properly. The js/css are coming from the same box as the rest of the MW installation, that's what's strange... maybe Yslow is just saying that there's multiple js and css being loaded from other pages, since they're literally loading from different urls into the same page.
