You might be able to revert them using userchrome.css (https://www.userchrome.org/megabar-styling-firefox-address-b...). And as "megabar" update has shown, this new "tab" style will probably be reverted in future redesign.

Did they really revert the megabar? I can't find anything about that with searches. (I fixed it to look exactly like the old design with usercss, so I can't easily check myself.)

As a side note, anyone using TreeStyleTab is probably immune from Mozilla's awful tab style revamp, as the tabs in TST are styled using CSS by the extension.

There was this comment about removing large Urlbar: https://bugzilla.mozilla.org/show_bug.cgi?id=1698656#c2

That's extremely funny, thanks. Kinda reminds me of what people have been saying about Google for a decade now - starting projects and sunsetting them with no coherent story or end goal. This case seems particularly ironic because they insisted on keeping the change despite widespread dislike.

Looking at latest Firefox Developer Edition, where new tabs and menus has landed, sadly the megabar is still the same. Sorry, if I misunderstood initial message and gave false hope. But hey, at least context menu is back to text back/forward actions instead of icons. Everything keeps going in circle.

That's what this is? Wow, the new tabs are ... really big. Lots of wasted space it feels... and the inactive ones have no border between them..?
