HERE IS THE ANSWER
Here is the answer to get TABS BELOW with Firefox V90 . . copy all of this code below the broken line into your - userChrome.css - file and save it.
You can modify the 45px in this line if you wish to get an appropriate height . . just experiment with different numbers till you get it right
--menubar-height: 45px; /*30px|41px=11px; caption buttons on menubar*/
Also to make the tabs wider or narrower, modify the line which is coded
width: 50vw !important;
Finally you must enable - css - in Firefox, by typing about:config into your address bar, and search for toolkit.
When all the toolkit options appear change the one which says
toolkit.legacyUserProfileCustomizations.stylesheets
to TRUE by click the icon in the right hand column.
Than close Firefox and reopen, and check how it looks
This will enable your - css - file to be read, and interpreted and accepted by the Firefox browser.
