Mee too... since Friday, Oct. 28.
Tab bar expands to as many (empty) rows as there are tabs, so after I open ~10 tabs, only bottom half of the window has browsing contents. Since I have around 40 tabs at all times, my whole visible Firefox is just tab bar.

Example is worth many words:

Tried to disable other extensions, but only disabling Paxmod alleviates the problem, in a sense that I can browse the 'net, but only with single row of tabs.

Aaah, I wasn't able to fix it in time. Should be patched now. Thanks for the early report.
