Like adding vertical tabs?

Having fucked an entire ecosystem of UI-modifying plugins, seven years prior. Still not matching the functionality of that decades-running, userbase-driven experimentation. I want my goddamn multi-row tabs back.

Mozilla doesn't get kudos for tiny improvements as if they cancel out huge blunders. Killing vertical tabs by killing XUL also severely limited DownThemAll, and they spent a year ignoring pleas from the guy that gave their browser and their browser alone the best download plugin to-date. He eventually managed to "just rewrite!" and claw most functionality back from Chrome's tightassed tool-kit. Most authors did not. Most authors had not, since the browser fucking launched. I can barely remember how much functionality I've lost, thanks to Mozilla refusing to respect plugin devs and formalize any lasting API. The best bits did come back, thanks to other authors who also missed those features... until they too burned out and fucked off.

But hey! Mozilla also made some clever tweaks inside the only software project that advertises their true passion for smartphones I mean chat I mean crypto I mean AI I mean $nextbigtrend, so it's squaresies.
