The user interface will be significantly redesigned in Firefox 157.
To enable the new interface without waiting for the release of Firefox 157, you can set the "browser.nova.enabled" preference on the about:config page.

The have used an ugly deep purple color everywhere in the user interface. Very fidgety for my old eyes.
And all these round buttons everywhere. Do they think my desktop has to become a smartphone or tablet?

It seems that Mozilla is determined to drive away the last loyal users.
I have been a user pretty much from the beginning and have accepted a lot, but this really takes the cake!
I also tried using a different theme (Classic Light). That does change the purple line around the URL box back to blue, but otherwise all the purple accents remain exactly the same!

If this is what Mozilla sees as the future, I am gone!

I will never update to that release. I will either stay with Fx 156 or move to an ESR version.

The problem is that my bank will not accept it when the version is too old. And they quite critical these days about updating the browser.
Then I would have to use a user agent switcher, but by that after some time I would have more risks.
I did use such an extension in the past, when I used Firefox ESR and the version number was not sent correctly by Firefox.
For instance: if I would use Firefox ESR 153.4 by the end of September, it would only report to the bank (or to any site) Firefox 153.
It stays like that, even one year later when the version is ESR 153.14. So my bank thinks I still am using 153.0 which by then is rather old.
By means of a user agent extension I could change it, but I would have to change that by hand after every update.'

By now I am seriously looking at other browsers. My problem is that I can't use Waterfox or LibreWolf, because their translation into Dutch language is not complete at all. Especially settings often are untranslated. I can write and read English, but for daily use I need a browser that has a correct translation into Dutch (and I'm not the only user in the house). Don't yet know what to use next.

I use the Firefox Theme, Red Fade, I do not have any purple whatsoever, just white outlines.

That’s strange; the bank should be checking certificates, not the browser version.
You could use MS Edge for the bank and Firefox for everything else (because of Manifest V2).
Maybe Chromium will work, only the official assembly from the dev channel

I just tried the new interface out and yes I don't like the purple interface and rounded corners either as it doesn't look good when using the "Dark space full transparent" theme, Hopeful we can still disable it using about:config in the future after 157 as "browser.compactmode.show = true" still works and Mozilla changed that long ago.

Also now that I think of it when I did a fresh reinstall of Firefox on my Insider build I wondered why the interface changed and was so ugly now I know why thank's @abactuon.

I've just tried the Nova interface and I'm undecided right now on whether I like it or not.

However, after fixing the little 'annoyance' here (thanks again das10) I now see that I have this (see image).

OK, Mozilla - I get it. You're trying to keep up with Chrome and Edge in what I consider to be a race to the bottom but I'm getting very close to dumping Firefox because if this is how things are going to be with your browser from now on then I want no part of it.

I might start looking at LibreWolf which is recommended by a few members here.

The Browser wars were over at one time, Chrome & MS Edge are to blame an not Mozilla. Firefox Nova can be avoided, it is hard to avoid EDGE.

FrancoDT · Sep 12, 2026

Given that Firefox is now a secondary browser for me I honestly don't pay a lot of attention to it's appearance anymore. I just keep it up to date and working should I need it for a certain website or event. Same can be said for Chrome and of course Edge my last resort.

CarlSD · Sep 12, 2026

I've downloaded LibreWolf but I haven't installed it yet. I have to go out for most of the day (9:30am Sunday here). I'll install and try it out when I get back.

If I like it (I'm sure I will) then I won't uninstall Firefox but I'll remove the shortcuts and make sure it cannot run or update 'behind my back' like Chrome and Edge have a tendency to do with 'default' settings.

Oh, I 'buried' Edge about 6 months ago and made absolutely sure that it cannot run or update when I'm not looking and I don't have or want Google Chrome. I use Helium for the occasional website that doesn't work properly in Firefox at the moment.

While not directly related, I had to update from my S20 ultra which was perfectly serviceable because my broker's android app would no longer work on older android versions. Older browsers can be less secure and not use the latest protocols.

The bank really checks the version of the browser. When that version is too old, I am not even able to log in. On trying to log in I get a popup window that my browser is old and suggestions which browser to use. That is the decision of the bank. I will not be able to change that otherwise than fake the browser is newer by using a user agent extension.

That is not a workable situation. Because if I browse products on webshops in Firefox and see something I like, I eventually reach the payment stage of the ordering process. I always pay using iDEAL/WERO, a Dutch/EU payment system that automatically links to my bank. If the bank operates via a different browser than the site where I am ordering, then it definitely won't work, and besides, it is too complicated.

About suggestions for alternative browsers: The UI of the browser of my choice absolutely needs to be in Dutch. Many alternative browsers have a very poor Dutch translation, that is not usable. My wife does not speak much English and can't use any English program. And I am writing now in English, but it's not my native language. And besides that, the browser needs to have a traditional menu like Firefox has. The only Chromium browser that has it is Vivaldi, which I have already tested and don't know yet if it fits my wishes. So please: for me no more suggestions about what alternative browser to use, I know what's in the market and will test them all (as far as I have not tested them yet).

Installed LibreWolf and I have to say I am impressed. Reminds me of what Firefox used to be like.

I've made it my default browser, I'll keep Firefox 'tucked away' and I'll check from time to time to see what happens with it regarding future updates but I don't think I will be going back at this stage. Shame, because I've had it as my main browser for about 20 years now.

I have a very low tolerance for bloatware and 'nags' that gradually find their way into browsers, operating systems and other software these days and it is getting worse by the day.

LibreWolf for my main browser now and Helium for a Chromium browser (if I need it).

Here, LibreWolf wasn't saving profiles; when reopening, it would reset. That's not what I wanted. Is there a way to make it save everything? The only problem I had with it is this configuration, and in some benchmarks I've seen, it's slower than Firefox. I don't know if they removed something used in Firefox that gives it more performance. I don't remember if it was just the profile or if it was the cache; all the passwords were saved in the cache, but LibreWolf didn't save them, which I hated, haha.
