Option to disable 'rounded' appearance

[Ben-Rogue]

I don't want this rounded mobile look on desktop, an option to change this in appearance would be appreciated.

Hi 

I want to be constructive and all, but the new rounded tabs look like something that failed in the early 2000s. Can we just not do that and stick with what works? 

PS: Please make it easier to opt out of all AI. Cheer.

I only joined because of this round things to upvote request to make this an option. I already found windows xp a pain and invested time to get rid of the round corners. And now I have to invest time again for firefox. The main issue, why I need an option. In an enterprise context I can't access about:config and can't use any of the ways provided. There please make it an option in the settings.

I would add to review. Give users the option to choose the corner radius for buttons, tabs, and blocks in the new interface, and everyone will be happy.

Firefox 157's rounded tabs are a regression, not progress. This is a direct copy of Chrome's aesthetic — and a bad one. If I wanted Chrome's look, I'd use Chrome. The rounded tab shape has no visual connection to the content area below it. It floats. It doesn't belong. That's basic visual design: elements that relate to each other need to read as connected.

The tab group feature — genuinely useful — is now broken visually. The colored indicator bar that used to work cleanly with sharp-edged tabs now sits disconnected from the group label. The only thing holding the group together visually is colocation, not design. That's lazy. Any senior designer comparing the before and after cannot seriously argue this is an improvement.

Favicons make the copy-paste problem obvious: most favicons are square or have mixed shapes. Rounded ones, like Google's, look fine in this design. Square ones look awkward. Firefox just optimized its tab design for Google's favicon. Think about what that means.

The default tab size is also too large now. On high-DPI screens, the OS already compensates for density. The browser doesn't need to overcorrect on top of that. Whoever signed off on these proportions has clearly not tested this on anything other than a retina Mac at 2x.

Nobody asked for this. Firefox already had a modern design. The people who chose Firefox did so deliberately — they're not here by accident, not lured in by Microsoft's OS-level Edge nudging or Google's wall-to-wall TV ads claiming Chrome is fast. Those tactics work on passive users. Firefox users are active choosers. You don't win them with visual mimicry. You keep them by being better at the things that matter: functionality, privacy, control. Every hour spent redesigning tabs to look like Chrome is an hour not spent on something that would actually make Firefox more useful. This redesign doesn't attract new users. It just annoys the ones you already have.

I'm a Firefox fan and lover. That's why this makes me angry. I've seen the other feedback — there's a lot of it. I'm adding to the count deliberately, because I want this to be the number one item on your backlog. Not because I enjoy complaining, but because someone on that team needs to run a real retrospective on how a decision this bad shipped. The question worth asking internally: did anyone actually challenge the assumption that Chrome got this right? Chrome didn't get it right. It just got there first.

Bring back sharp tabs. Reconnect the tab group indicator. Recalibrate the default density. Firefox deserves better than this — and so do its users.

I really like the new ui, and I hated the previous one; however, there should still be a choice.

Also, there are small bugs, but for me, it's still better than before.

BTW: For anyone wanting the old look, you can use the Proton theme; it is really easy to set up.

Hey guys! 

Not sure, who is still fascionated with ROUNDED design, Google who made it, and it is awful!!!!. No options to change such appearance...
