I've installed the Tabbed Browsing extensions on Firefox 1.0 (final) on Fedora Core 2 & for some reason I can't configure it to close a tab when I middle-click on that tab, that options is greyed out for some reason. The middle mouse button works as I can use it to open links in a new tan without problems but I would like to close these tabs when I middle click them. Right I have to double click a tab to close & it's not as comfortable.:dead: I've looked at the known problems list for that extension ( Tabbrowser Extension but it's nowhere to be seen (I've sent the programmer a link to this thread btw). Any ideas ?
