I love Firefox's tabs.
One improvement I'd like to see: to close a tab (a very common operation), you have to right-click it and then select close tab. Two clicks for a common interaction. To make matters worse, there's a big red button next to it that closes all tabs, not a common action, inviting mistakes.
What would work better: bring the close-tab functionality to the surface, and hide the close-all-tabs functionality under a right-click. Something like the image below.
If I find some time I'll open an account, read the FAQs and do a Bugzilla report. Meanwhile, if someone else wants to do that, feel free.
