I'm using Safari
It looks good, feels fast (although I haven't done much comparison). But tab-groups connected to focus mode really seals the deal for me.
The one thing I do wish for is more extensions, but most of the key ones I need are fortunately available.

Brave with uBlock Origin, AdGuard AdBlocker and Bitwarden.

Brave is beautiful and I love it a lot! I used it as my main browser for a couple of years and still use it as an alt to firefox, which is now my main :))

I use ffox for syncing & the mobile experience while I continue to use Brave for the dedicated user profiles :D

Safari

Firefox works very well on my Mac. That's the one I use

Safari most of the time. Occasionally Edge when I need to test things. It's pretty wild that I can run a Microsoft browser on macOS. Hasn't been that way since the 90s. :D

Firefox for work related stuff. Safari for personal browsing/logging into services (run credentials through keychain).

As others have said, Firefox & Ublock for the win!

Safari works fine for me

I find myself using Brave for most things currently but I do still use Firefox. I usually end up switching my primary between the two every couple of months.

99% Brave 1% Safari for me. Mostly Brave for cross platform sync.

Arc is wonderful once it 'clicks', but may feel slightly weird at first. I've been using it everyday since I got the invite (switched from FF).

Arc! No plans of going back!

Tried Arc. Was fun for 6 months as different but just went back to Safari as it at least just works.

Brave and Safari

I used to be a Firefox fanboy. But they don't care for resources and just eat ram and cpu for lunch. So, it is not usable for me, unless I close all tabs all the time - which I don't like.

Currently alternating between LibreWolf and Brave. I tried Safari when I first got my Mac but it sucks.

Safari for regular use and Brave for anonymous / testing stuff (science)

I'm using edge on a MacBook that I have.

I use Firefox because it lets me use Tampermonkey, and because I also use a Windows PC for gaming.

DuckDuckGo for Mac.

Vivaldi for most things, hardened Firefox for private browsing, tor for sensitive searches

I use Brave.

However, sometimes the privacy settings are so good that certain sites don't function as well, especially if there is a pop-up element on a site.

I switch the OS I’m using constantly, so I use Firefox cause of its pretty nice syncing features and pretty nice dev tools. Though, I have to use Chrome or some flavor of it for testing.

I actually really like Safari and its syncing within the ecosystem is quite handy, but I mostly need something that’s as good on Windows as it is MacOS.

Does anyone else have issues where images copied to the clipboard from Firefox don't paste? They always paste as blank objects for me. Safari and Chrome handle it fine. I would prefer to stick with Firefox if possible.

Chrome and Firefox but I really want to switch to just Firefox. I wish Firefox had multi user accounts and tab grouping since I rely on those two features all the time.

@rebiots was on chrome for a bit but went back to Safari for the ecosystem features but leaning towards doing a Safari/Firefox split

I primarily use Linux nowadays, but when I go back to my M1 Macbook Pro, I tend to use Safari. For me it's all about battery life. I'd love to use Firefox, but the battery drain compared to Safari is very noticeable.

Safari.

Firefox on my personal machine and chrome on my work machine.

80% Firefox nightly 10% Chrome and 10% Ferdium

Arc for me too (previously Firefox) - really been enjoying the experience

Firefox because of its wide variety of addons and cause I sync between a Windows PC

Safari for personal use and Opera (chromium) for work (webdevelopment).

Firefox. I love it’s dev tools and Mozilla has the internets back.

I am heavily into the Apple ecosystem. My whole life is on Apple’s platform. So, I use Safari. I do though, have Arc, Vivaldi, Edge, and Chrome installed.

I have an old Mac (RMBP 2014) and I really want to like Safari, but the fact that it feels slower than Chrome and that I don't have an iPhone anymore really makes it more difficult.

Safari (with Wipr), and for work Firefox (with ublock origin) because of compartmentalization and because MS Teams works (in Safari you need to disable cross-site tracking which I don't want to).

Mostly Brave for daily browsing. But for work, I use Microsoft Edge.

Add me to the Arc group. Absolutely the best and most game changing app I’ve used in years.
