Did you know that Firefox has a little hidden secret under the hood? It has a very nice minimal theme that comes in light and dark versions.
Update: The config setting is gone. However, this extension will help. It only works with dark mode though.
To enable it, open Firefox and type about:config in address bar and hit enter.
More than likely you’ll get a warning and just say that you’ll be careful.
Once you’re in, enter browser.devedition.theme.enabled in the config search box and then double-click it to enable it.
Firefox’s minimal theme should now be enabled. If it’s not the color you want, type devtools.theme in the config search box, double-click on it, and switch the value from light to dark or vice versa.
That’s it. Enjoy the minimal, beautiful version of Firefox!
To un-do the changes, just go back into the config and double-click on browser.devedition.theme.enabled.
This works in the latest version of Firefox. I’ve done it on the Mac, and I’m pretty sure it’ll work on Windows too. Linux? Why not?
