I still can't believe there isn't a fix for the missing close buttons!! Developer, are you alive?? This NEEDS to be fixed!! If it's because of a conflict with Tab Mix Plus, please talk to the developer on his forum at http://tmp.garyr.net/forum/viewtopic.php?t=10888&postdays=0&postorder=asc&start=2700&sid=7a33993414fa76e5cfe87d82e4aac5a3
Great idea and a major enhancement, but because of the bug that the others have mentioned here - the disappearing tab close button- still flawed. To keep the add-on useable despite that bug I use the double clicking on tab closes tab option in tabmixplus which works fine, but nevertheless I hope that bug gets adressesd in an update.
Looks neat, but it is not compatible with Tab Mix Plus 0.3.8.3pre100515a apparently. It makes the tabs about and inch and a half bigger instead of a few pixels. I'm using Firefox 3.6.4 on Windows 7 32-bit.
This is a nice concept but made my browser a bit different from the preview pic. On the official latest version of Firefox 3.5, the fonts on tabs doesn't change its size. I uploaded the captured image on http://goo.gl/xr9f
