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.
Thank you so much!
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.
We’re just going to alternate between making UIs more round and less round for all eternity.

Meh.
I’m old. I miss the way Mozilla Suite and Netscape looked. The more of these “modern” trends that pass by the more they all look the same to me.
Thankfully Thunderbird is less affected by bullshit like this. As long as I can view my daily feed through RSS in table view, I’m happy.
It’s not so bad. Since everything is pill-shaped I more often remember to take my medication. :3
Thank you. I’ve read your post yesterday morning and in the afternoon I had to face the change. I came straight back for the fix.

WTF were they thinking with the new design; it’s so incredibly ugly? Thanks so much for posting this.
I like it, so this must be all my fault. Sorry, everyone.
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.
This is what I use. There’s even a flatpak app to keep the theme up to date for
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.
every day i read tech news and am vindicated in my decision to run debian stable, maybe i’ll see this new ui in 3 years
EDIT: well, this is ironic… within the past 24 hours, debian trixie-security has bumped firefox-esr from 140 to 153…
Thank you. The UI was perfectly fine before, now everything’s a shiny circle.
Speaking as someone who’s colorblind, I rely heavily on shapes, straight borders, and strongly contrasting colors to be able to tell the difference between objects and the boundaries between objects.
Nice that Firefox is throwing all colorblind people under the bus(~5% of the population) in the same way Apple has been doing for years.
Its gonna be gradients isn’t it.
I haven’t seen the new design yet but here’s the blog post for those curious
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.
Aero was probably the last time I ever saw a new interface style and thought it looked cool. Now it’s just endless reshuffling of parameters. Maybe we just arrived at the ideal set of parameters to reshuffle and any major change at this point could only make things worse.
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.
I’ve been using Lepton/Firefox-Ui-Fix for about 5 years now and haven’t had to worry Ui updates since.
