looks like rendering adblockers extensions obsolete with manifest-v3 was not enough so now they try to implement DRM into the browser giving the ability to any website to refuse traffic to you if you don't run a complaint browser ( cough...firefox )
here is an article in hacker news since i'm sure they can explain this to you better than i.
and also some github docs
Such a shame. I love the Arc browser, but in my eyes its days are numbered. Then it'll be back to Orion.
What's so cool about it? Not being a smartass I'm genuinely interested. Their website is cagey and their youtube is talking heads and fluff.
Yeah, their marketing and outward appearance is a little strange. I think it's something they need to work on.
It just has a lot of productivity features, like having a fleshed-out vertical tab system, built-in split screening for tabs and being able to separate all my stuff into separate "spaces" that I can assign to different profiles and switch between with a swipe.
Everything in the browser can be accessed from a "command bar" (similar to Spotlight) meaning I can navigate the UI a lot faster. Every keybind (as far as I know) can be changed to whatever you want.
The boosts are pretty cool too. Basically lets you quickly change the colours, fonts, etc as well as "zap" elements (similar to uBlock Origin) and inject css and js. The changes persist and are toggleable through the UI.
Also, I just really like how it looks. It fits really well with the aesthetic of my Mac setup.
It's got its downsides; being based on Chromium makes it less battery efficient than Orion, which is based on WebKit. Plus it isn't open source, and vertical tabs aren't for everyone, but it works great for me (until Google kills Manifest V2...)
