I know.

It is also clear that this is a hacky workaround that is not guaranteed to continue working.

And the new tree style tabs is quite unstable compared to the old 'bad' plug in which results in it sometimes being very handy that the other tabs are still visible. I'd love for them to be gone too, they take up vertical space which is at a premium but then Mozilla should first give extension developers a chance to get the kinks ironed out. Such unforced errors are really annoying.

They also keep threatening to remove userChrome.css (or at least adding more leopards), and I think the day that happens may be the day I throw my hands up and stop using Firefox. Although I don't know what I'll use instead. I guess I'll have to contribute a pile of patches to `surf` or something.

Yeah instead Addons have to direct the user to manually modify CSS, thus perfectly protecting the sanctity of the browser UI for all time.

Mozilla, I'm going to use very small words here so that you understand: users will want to change your UI. You can't fight that without fighting your own users. Then again, that doesn't seem to be stopping them.

Mozilla understands that very well. Otherwise userChrome.css wouldn't exist. They just made it so that it's abundantly clear that if you screw up your userChrome.css, it's your fault, not Mozilla's.

Yeah, which is bullshit.

You can't both say "well we let you do it, we're so customizable" and "but if you do and anything goes wrong, it's your fault."

I'd rather that userchrome get removed and Firefox own up to the fact that they're not gonna properly support what users want.

A company who puts users first should not be ashamed of supporting their users' desires. You either support your users or you fight your users. Mozilla have somehow decided to publicly fight their users and furtively and abortively support them in secret; I really don't get how they think that reflects well on them. It feels like Moz are more trying to appease their own UX designers than their userbase.

A better solution would probably be to add a proper API to move the tabs around and then some possibility to customize them.

FWIW Mozilla even experimented with vertical tabs, only they made the tab column so high it interfered with the URL bar and also didn't support nesting.
