If you are like me, you need this addon and are willing to install a dev version: LINK
I can’t stand having to scroll through tabs in a single row…
UPDATE: Just to be clear, clicking the link above will initiate an installation of a Firefox Addon. Please see the comments of this post for clarification. (thx Luis)
Might be better to link to the download page instead of the direct download. Not just so we can avoid a surprise download, but also so we can better understand what it is we’re downloading. Now I have a file, no developer page, and only a slight idea of what it is. Care to elaborate?
Sorry!
You can read about this addon here:

and also at its mozdev page here:

And of course, it would be better to wait for a stable version to come out especially for FF 3.5.
