Missing style for buttons in tab toolbar

[ArkadiuszMichalski]

Now we can set style for buttons in menubar/nav/bookmarks toolbar:

@import "./css/buttons/buttons_on_navbar_classic_appearance.css";
@import "./css/buttons/buttons_on_bookmarks_toolbar_old_size_and_appearance.css";
@import "./css/buttons/buttons_on_menubar_toolbar_classic_appearance.css";

but not in tab toolbar. This was possible in past through Classic Toolbar Buttons.

General problems (join general discussion thread to talk about Firefox bugs):

• CSS code might not work, if multi-process mode (e10s) is disabled
• CSS code imported through userContent.css might not work on macOS/Linux
• no support, if code contains '@namespace' references (remove that useless stuff)

I have not offered any styles for buttons on tabs toolbar, because in Fx57+ those styles always broke tab height especially after Mozilla started to add strange padding and margins to them, but I will look into it.

Can you briefly explain what this is physically pointing to as far as location. @import "./css/buttons/buttons_on_bookmarks_toolbar_old_size_and_appearance.css"; Is that still there?
Now I found that my CSS code was compromised with the first part being modified like this =@import "./../buttons.....
The 89 update broke my tabs and put them at the bottom of the screen. I replaced the code with Tabs-not-on-top, and it broke the 3+ line for the bookmark muti line CSS. Can you help?
