i use https://github.com/Aris-t2/CustomCSSforFx to "freeze" my preferred firefox look
3. https://github.com/Aris-t2/CustomCSSforFx has tweak to have multi-row tabs. I use pretty much switched to FF just because of this.
https://github.com/Aris-t2/CustomCSSforFx has some tweaks to make it less annoying.

Unfortunately userchrome.css breaks frequently with firefox updates and is a pain to maintain since it is outside of the extension ecosystem.
There used to be a great addon called ClassicThemeRestorer that got killed during firefox's terrible web extension debacle. It lives on in https://github.com/Aris-t2/CustomCSSforFx but different parts break everytime the fickle designers at mozilla change their mind on what a tab should look like.
I've used https://github.com/Aris-t2/CustomCSSforFx ever since ClassicThemeRestorer broke when they killed the old extensions. It seems to work fine for me.
Yeah, I resisted the upgrade to FF Quantum for a while, but ultimately made the move and it's worked out well. The biggest things I needed were a WebExtension version of Tree Style Tabs, plus the restyling options from https://github.com/Aris-t2/CustomCSSforFx .
You can still tweak Firefox internals but you have to resort to its native `userChrome.css` [0] since current extensions API does not allow access to every corner. Luckily you can use devtools for that [1] what makes it quite pleasant (at least you don't have to restart browser to see the change). You can use pre-made package ([2][3]) and toggle what you want.

For Classic Theme Restorer withdrawal, try custom userChrome.css code.
I also lost my window, but it was in the "recently closed windows" menu, so no big deal. Most of the (all?) changes that you got with Classic Theme Restorer can still be accomplished with userChrome.css. Check this[1] github repo for the quickest way to set it back up the way you like it.
Have a look at https://github.com/Aris-t2/CustomCSSforFx , it can do many things, even if it's not a perfect Classic Theme Restorer replacement.
