I want both. I want a stable ordering, which is roughly the order that I opened the tabs. And I want a recency ordering, to be able to quickly switch between the most recent handful of tabs I'm working with. Fortunately, I have exactly that already. The native tab bar gives the stable ordering, except I ignore that because I'm a tab hoarder and only look at the Tree Style Tabs sidebar. Ctrl-Tab gives the recency ordering. I certainly have complaints about how TST isn't able to provide all of the native functionality (eg the Send Tab To Device menu is empty, and the stupid native tab bar is still visible without a userChrome.css hack). But in terms of ordering, Firefox already gives me the two different orders I care about in a form that works for me.
