Not a fan of the new look. If you’re in the same boat, plug:
about:config
into your URL bar, and search for:
browser.nova.enabled
Toggle it to false using the button to the right.
There are functional changes that Nova also introduced: this won’t effect those - only the aesthetic.
I like it, so this must be all my fault. Sorry, everyone.
sigh…pills. one of the worst trends in UI design within the past couple years. pills, borders for everything, purple, jetbrainsmono. and Firefox decided “pills is the way to go!”. It’s what i’ve started calling “The Claude Look”.
I really hate the pills look.
doing A : B testing with that toggle. It’s definitely hard to see it as anything but a UI downgrade.
The toolbar icons have a blurrier look on my computer on Nova? They just look worse too imo design wise.
Thanks for this. I was open minded until I saw it for myself. Your post fixed a problem I didn’t know I was about to have.
I wonder if people still think about these changes or it’s all just scripted now. This time we make things a bit rounder, next time a bit less, add a tiny bit of space here, take it off there, more gradients or less. All the while pretending that it’s more modern or something when it’s actually just another combination of the same shit. I don’t mind, I just find it odd that anyone cares or thinks it’s somehow new.
Staff meetings where employees must justify themselves to out-of-touch bosses.
If you only dislike the horrible AI-looking color scheme, you can install the Proton theme (by Firefox) from the settings.
In case you prefer a store link: https://addons.mozilla.org/en-US/firefox/addon/firefox-proton/I honestly have no idea how anyone thought this disgusting mess was a good idea to roll out to everyone.

Bro I am still reeling from firefox 4 don’t do this to me again
Is it again a css
!force;over the old style?The new UI is fine for me, but it’s also nice to see they kept the nova.enabled flag after the update for those who don’t want it.
The best change for me was moving compact tabs from an about:config flag to an actual setting. Was using that before and it’s nice to see it’s not going away after all.
Seeing the blog post I wasn’t sold on the changes, but I thought to myself it’s usually just a matter of getting used to it.
Then I realized I’m reading this from GNOME Web and I hardly use Firefox at all any more. For the first time I will not get used to it. Then I saw the links to Twitter and Linkedin, and remembered exactly why I left that trainwreck behind.
Firefox has long been the most customizable browser. It’s in our open source DNA. Now we’re adding more ways to make Firefox feel like yours, including new themes and wallpapers.
You used to actually be able to theme Firefox, is this returning? All you have now are crummy backgrounds to clutter the visually bland buttons and menus.
Edit: this was meant as a reply to the post linking to their blog. And it looks like the answer is ”no, eat your porridge”.
People still write full ui CSS overhaul sorts of themes, does that not count…?
Do you have an example? I tried finding a theme that makes the browser look like Netscape Navigator, but the ones I found were lackluster. The icons on the buttons didn’t even change.
I’ve been using Lepton/Firefox-Ui-Fix for about 5 years now and haven’t had to worry Ui updates since.
WTF were they thinking with the new design; it’s so incredibly ugly? Thanks so much for posting this.
Oh thanks! I was waiting to try it out. Gonna update now to enable it. Looks nice.
