Quick Steps
about:config
and press enter.uidensity
0
value of browser.uidensity
to 1
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. browser.uidensity
. It sounded like what I wanted!
browser.uidensity
is set to 0
by default, but if you double click it or press the Pencil/Edit button on the left and change the 0
value to 1
. The change takes immediate effect! That's it!
Enjoy your additional 13 pixels!
And of course, if you wish to revert the change, run through the process again and press the Reset
button next to the Edit
button, or simply change the 1
back to a 0
.
You can also revert in the GUI. Changing the default value of uidensity
enables an option in the 'Customize Toolbar' page. Selecting 'Normal' here will get you back to defaults.
