After Firefox 89’s interface update in 2021 there was a not-so-subtle change made to the way tabs were displayed. They floated now! A neutral change, in my opinion, but something else happened, too. They grew, and were now taking up additional space! How much? I’m not quite sure, but they’re definitely bigger by a few pixels.
This didn’t bother me enough to go searching for a fix immediately. No, this was a “I’m bored, I wonder if there’s a fix for this” type situation.
So there I was, poking around in
about:config scrolling through options, changing things, reverting them, and then I came across another that looked intriguing.

0 value to
1. The change takes immediate effect! That’s it!
Enjoy your additional 13 pixels!
