I don't know what to tell you then. I'm typing this comment right now using Firefox, with a tab-bar full of tabs, and every visible tab has the favicon and a portion of the title visible. The rest can be found in the drop-down, with nearly the entire title displayed.
Maybe there's some setting that controls this behavior, but my Firefox is pretty much completely stock. shrug
Interesting. Maybe we're running different versions, or maybe it's somehow dependent on screen resolution or something. Weird. For me, Firefox has always displayed at least the first few characters of the title.
