The latest update to Firefox broke the display once more by moving Tabs to the top.

I searched and eventually found a fix on Mac’s site – The Foggy Mirror.

After a couple of failed attempts I eventually found how to do it.

1. Copy the code provided in Mac’s link’
2. Type about:profiles in the address bar.
3. At “Preofile: default -> Root directory” click on “Open Directory”.
4. Enter folder “chrome” or create it if it doesn’t exist.
5. Save the copied content as a file “userChrome.css” or replace an existing file.
6. Restart Firefox.

This fixed the Tabs location but I wanted the Toolbar on top. I found the fix for that on Mac’s link too.

1. Copy the code provided here.
2. Paste the code at the end of the userChrome.css file [as above]
3. Restart Firefox.

I did try the second block of code on its own but that broke the site again. With the two blocks together my Firefox is back to its original appearance.
