Since Opera have in their wisdom decided to make their market share even smaller by dropping the option to move the tab bar. It means I have to find a usuable browser that has this feature.

So please can you make moving the tab bar to a horizontal position an easy operation in firefox. I've not yet mastered it and on my Manjaro OS the .mozilla folder contains only an extensions and a firefox folder. There is no profiles folder. So where do I create the userChrome.css ?

I strongly recommend that you save yourself the trouble and use Stylish instead.

If you insist on using userChrome.css,

  1. Type about:support in the address bar and press Enter.
  2. Click the button labeled Show Folder or something similar. That opens your profile folder in your file manager.
  3. In your profile folder, create a folder named chrome
  4. In the chrome folder, create a new plain text file called userChrome.css
  5. In userChrome.css, put the following at the top of the file, and any CSS code below.
