Apple

Safari and Firefox. I use Brave on my iPad, but I'm trying to keep my Chromium based browsing down.

Vivaldi mostly

I use Safari for personal browsing and Chrome for work (internal corporate stuff)

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

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

When it comes to personal stuff I only use Firefox, regardless of device. But as a web developer I end up having to use them all at various times, and Safari isn't too bad.

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

Safari works fine for me

A hardened Firefox fork, librefox

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).

Brave with uBlock Origin, AdGuard AdBlocker and Bitwarden.

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.

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!

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

Firefox, although also looking for a very lightweight privacy friendly browser.

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

Safari for anything personal (for easy sync with my other devices), and Edge for work stuff. Safari meets all my basic needs in a browser, and iCloud Keychain has been great.

I use Microsoft Edge, Firefox and Safari. I like using a browser that is very similar to Chrome, but I rather avoid Chrome. Edge was also forced for using Bing chat for some time. Safari is fine, but you can't use all the plugins that are available for other browsers, and that is a bit annoying.

I used Firefox a lot before, but some websites that I used had some annoying bugs. I'm also a bit more used to the dev tools of Edge. Of course, I test websites that I build on all 3 browsers, and often have more than one open at the same time.

Brave for web browsing, Safari for video streaming. As far as I know, Edge on Windows and Safari on Mac will stream in the best quality possible due to DRM/codecs. Supposedly Safari uses less battery streaming video on Mac too.

Firefox but currently exploring Orion + Kagi search to see if I am going to switch. Heard about Kagi on kbin and it seems awesome so far.

Tried Arc for a while, really enjoyed it but right now I'm using Edge (just as a test of the MacOS version). Used Orion in the past and liked it but I'm waiting for some updates before I commit to it full time (extension API still being worked on, no auto updates for extensions, etc). I've basically used them all at one point or another.

Firefox. I'm trying out Arc Browser but it's been so sluggish.

Firefox and sometimes Safari. Since I also have a Windows machine I like to use the same browser on both devices. And I don‘t like giving more data to Google by using Chrome. They know enough about me already

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).

Firefox on MacOS. I really believe in Mozilla as a company. uBlock Origin is one of the better ad blockers you can find. Safari is a bit easier on battery life though.

I am stuck on Edge on everything. The vertical tab implementation on Edge for me outdoes anything else. I can't go back and no addons do the same.

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

Firefox and Safari.

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

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

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

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

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

I use Firefox with uBlock Origin. Not as nice on the battery as Safari or Brave, but I've always liked and preferred Firefox.

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

I use Arc and Firefox. Arc is fun and daring, so I'm curious where it goes. I especially like their Spaces, which makes it simple to separate different contexts (e.g. work, personal, entertainment). Not only by cache and cookies, but also visually.

Chrome for personal use, Brave for work. I used to use Firefox but I need tab groups and I'd prefer a native solution for that. Simple Tab Groups seems unstable.

Firefox on Linux machines at home. Mostly Chrome for work on the MacBook because the employer uses Google for everything.

DuckDuckGo for Mac.

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.
