Hello everyone!
Many of you have noticed some of the design updates appearing in certain Firefox configurations over the past few months. Internally, we’ve been calling this work Project Nova, and today we’re excited to share a deeper look at what we’ve been building and where we’re heading next.
The goal of this work is to create a more cohesive foundation for Firefox: making the browser feel cleaner, warmer, faster, and more adaptable.
Some of the areas we’re working on include:
The redesign work also focuses heavily on cohesiveness, accessibility, and making Firefox feel more consistent across desktop and mobile experiences.
This work is still evolving, and we want to continue building this in the open with all of you.
As always, let us know what you think below. We’re listening.

it's technically impossible to make it native, it may be possible to mimic to some extent, but having an entirely separate GUI for one system while copying behavior and custom elements from the proprietary one is just out of question

Well, we shared more about Project Nova...and collected a lot of great feedback (thanks!)...and now we're ready for you all to take it for a spin in the latest version of Firefox Nightly.
The team working on Nova just kicked off a new discussion thread with more info on the latest updates and also how to test it - check it out here: Take Project Nova for a spin in Nightly!
As always, it's a great opportunity to share feedback and interact directly with the Firefox team. Hope to see you all there 😀

I know it would be not easy to implement fast, but Firefox would benefit from:
1. Having ability to optimize screen space as user wants(Think: Compact UI - Standard UI - Touch UI), specifically to make sure that users won't feel like their software using their monitor inefficiently.
2. Add ability to change curves, with option to change curvature of top-right-bottom-left akin to how Vivaldi done it.
3. Option to turn on Liquid Glass-esque effects, that can make browser look nicer and cooler.

hi 🙂 Thanks so much for your feedback. I know the answers to 2 of the pieces of feedback so I'm going to share.
1. With Nova we are going to support Compact UI, Standard UI and Touch UI. We've added UI to select between the options in settings under the appearance area.
3. We've started to look further in Liquid glass effects. We started to last year but it needs more attention before we're happy with a solution. We want to make sure we support all the platform features while not causing any performance or design issues.

I do not want Liquid Glass on Android and Linux

Please make it optional. I like the square corners, rounded looks terrible to me.

exactly, I like rounded corners, cause these stubborn Windows rectangle layout hurt the eyes;-) Ivy won't even loose a word on this crap layout.
Design is a question of "form follows function", and if we let these windows fan boys take over ruling of Firefox layout, **bleep** is pre-programmed. But hey, their problem ...

I'm not in love with the perimeter around the app. Am I alone here? It seems like it's there more for aesthetics than functionality, and it's taking up space that's probably not needed. Especially when maximized. But, if it does stay...
On Windows when maximized, I'd love to be able to whip my cursor up to the top-most pixel and be able to drag down and pull the window out of full screen, but the entire perimeter is functionally dead and does nothing on click, drag, or right-click. If the top-most border at least behaved like a title bar and allowed you to move the window around, that'd be a huge help.
EDIT: I just had a non-clickable URL selected and tried to drag and drop it onto the tab bar, but ran into the same issue. Naturally dropped it at the very top, but the top is the dead border now so it did nothing. This is going to take a while to get used to 😔
While I rarely click and drag on scrollbars, having a deadzone to the right of a scrollbar makes it much harder to click on, especially with it being so narrow nowadays. But I think that's probably not a huge issue. Just figured I'd bring it up since it's another drawback to the perimeter.

The Scrollbar not being clickable from the very Edge is a big Issue.
I drag Scrollbars all the Time.

What I'd like to see is more personality in the new look. For example, the throbber animation in the tab when a page is loading, why not have kit (or just their tail) run/jump across the tab while that's happening and then jumps away when its done loading, or a splash of colour representing a container when you open a new tab container, or anything else that would make the browser distinctly Firefox, and/or give someone a smile when they see it. Given that you're trying to get users to accept something new, I believe the new look needs to induce these moments of joy to really pay off.

The rounded corners aren't enough please increase them more.
01-08-2026 09:31 AM
I am trying out Nigthly. An immediate problem I have encountered, which seems like a deal breaker to me, is that in full screen when I rush my mouse cursor to the very top of my screen, I can not click on the tabs! The tabs now have a padding on top and the area is not clickable. This provides a really poor UX for such a use case. I appreciate the work on the redesign and I hope you will hear my feedback, thanks 🙂

- i definitelly had to switch to compact mode.
- i don't like the round stuff... please bring an option to get back to more corners. (i also use waterfox and i love the minimalistic visual style. i am relatively young and preffer the oldschool small UI elements.)
- please reduce the "verticalism". These days everything gets the vertical smartphone look, which results in only using 1/3 of the screen. anoying and a waste of space. Please give an option for more "horizentalism".
(The vertical trends cause that less info is shown at once. People with ADHD would truely benefit from seeing as much info and current position of navigation at once as possible!)
anyways still way better than all chromium based browsers 😉
and keep working on PWAs 🙂

Nova theme compatibility
Nova currently seems to break compatibility with some existing theme settings. There are quite a few UI elements that either aren't addressable through themes at all, or don't consistently use the colors specified by the theme.
I've marked the affected areas more clearly in the attached pictures.
Elements that aren't properly addressable using themes
-Some UI elements, such as the border around the search/address bar, don't seem to be addressable through theme headers.
-The search bar color is slightly different from the color specified by the theme.
-The inactive search bar doesn't follow the rest of the theme and appears to use a different color. It also doesn't seem to be independently addressable.
-With vertical tabs, the tab background/color doesn't match the rest of the theme. It appears to be tied to the toolbar/search menu color, rather than using the appropriate theme color.
-The default purple Nova theme doesn't seem to be fully reproducible/addressable using the available theme headers.
-The background color of pages such as Settings, About, Configuration, etc. doesn't appear to be properly addressable using themes.
-Likewise, the background color of the sidebar/settings menu doesn't seem to be addressable.
Theme header inconsistencies
Some of the theme headers also appear to be broken or behave differently in Nova, particularly with the vertical tab configuration.
There also seems to be some inconsistency in what a particular header controls depending on the configuration. In other words, the same theme header can correspond to different UI elements in different configurations, which makes themes difficult to maintain and can cause them to break when switching between configurations.
These should consistently control things like the selected/highlighted text color and the default text color in the field, but the behavior doesn't always seem consistent.
It would be great if Nova could make these UI elements consistently respect the existing Firefox theme headers, rather than introducing additional hard-coded or indirectly controlled colors.
Also, as a separate UI suggestion: it would be nice to have an option to hide the URL bar icons, or only show them on hover, for a more compact/minimal address bar (See the last picture).

The Tabs really do not look and feel good. They seem disconnected which makes the Browser feel dreamy and floaty, in the bad Way. I associate it with the Instability of Dreams rather than the Creativity of Dreams.
And it doesn’t even look fun. It’s bland.
I propose a much more grounded and dynamic Shape: Sharp Corners at the Bottom, rounded at the Top.
Also note how the rounded Corners use a Squircle Shape, not a Circle Shape. And how the slim “pinned Tabs” are optically compensated by having noticably less Rounding at the Top. I didn’t think about it when i was drawing it, it came naturally because i was drawing it and not designing directly in Software.
This Drawing shows how it would look like in the horizontal Tab Bar and in the vertical Tab Bar.
I feel the Color Gradient should also go from top-to-bottom, not left-to-right, because the darker Color being at the bottom would also suggest Weight in a pleasing Way.
Finally, as a Part-Time UI & UX Designers myself, i have a valuable Design Philosophy: Always design as a crude Drawing first because the best Ideas only come from that tactile Experience, which is free from the Constraints of existing Computer Code. Wherever possible, the Computer should be for implementing Designs first made by tactile Means, not for making new Designs from Scratch.
