> Chrome and Opera squeeze the tabs, but list them all, whereas Firefox forces a scroll after so many, which feels horrible. Also Opera has let's you list and switch open tabs with CTRL+TAB, or lets you reposition your tabs.

I use this tiny add-on, written by one of the main Firefox front end developers: https://addons.mozilla.org/en-us/firefox/addon/custom-tab-wi...

It makes Firefox have the Chrome behavior of making tabs shrink infinitely. All it does it tweak one minor setting in the UI, so it's pretty bulletproof.
