I made a version which works much better for me - in which all tabs are smaller and not expanded on the last row. Instructions;
- Type about:support in url field of firefox, hit enter.
- On the ‘Profile Folder’ setting (about 8th from the top) click the ‘Open Folder’ button.
- Create the ‘chrome’ subfolder, if you don’t already have one.
- Inside that folder create a file called ‘userChrome.css’ (right click > new > text document - make sure to name the file userChrome.css and not userChrome.css.txt or something)
- Open the file for editing and paste the contents of this file;

Into it. - Restart FF and you should have multi row tabs
- Enjoy!
Btw, there is still a small problem (also in the original as far as I can see); it’s not possible to drag tabs well from one row to another. Any Firefox GUI expert who can fix this?
God bless!
