When many tabs were opened, the tabs shrunk in width until only the page icon (or downloading throbber, if the page was still downloading) was visible. I'd like the option to allow tabs to get that small in the current build, as the default minimum tab width is far too wide for my preference. Reproducible: Always

about:config browser.tabs.tabMinWidth This is wontfix, or invalid depending on whether this is what the reporter wants, or if UI is also requested.

See comment 1 - note that you need to restart for it to take effect. UI for this pref was wontfixed elsewhere.
