I remember so odd not so transparent stuff not working well when I tried it years ago, like throttling of cpu/gpu, fan control, sleep modes, stuff like that. Provided your hardware is fully supported though I think they provide an excellent experience.

Maybe I should try to rebase my home server to freebsd …

Ublue provides a really solid base template that makes it very easy to do stuff like this, all the heavy lifting of a distro is done by fedora, ublue adds the codecs and drivers and build system for updates.

Wouldn’t be unreasonable to make your own distro with it honestly.

There is literally a gentoo-install: https://github.com/oddlama/gentoo-install

They are deprecating the underlying technology(called manifest V2 or MV2 for short) and replacing it with a different one(MV3) that lacks some of the capabilities for some kind of adblocking.

So yeah, it’s pretty much dead on chromium. The developers of brave have commited to provide a best effort support for their browser though: https://brave.com/blog/brave-shields-manifest-v3/

Firefox on the other end has no intention of deprecating support for MV2 so any browsers based on that are fine. Keep in mind MV3 supports some adblocking and some Adblockers have already moved to it, it’s just a lesser extent.
