simple-tab-groups VS xnu

The older release is still available on that page, but presumably with different features. Development looks very active here: https://github.com/Drive4ik/simple-tab-groups/tree/master/plugins/stg-plugin-group-notes

Are there reasons that the "Simple Tab Groups" extension isn't suitable for you? It seems to be well-maintained, cleverly uses Firefox's "hide tabs" API to keep a single window behind-the-scenes, and has integration with lots of other features like Firefox's containers. I think it's an indirect descendent of the old Tab Groups extension when it was spun out of Firefox.

Just use Simple Tab Groups honestly

I assume that the speed is partly a consequence of not integrating with the context menu items of other extensions and of Firefox. See for example the discussions at and around https://github.com/Drive4ik/simple-tab-groups/issues/749#issuecomment-783171538

tab grouping extensions that do not misuse Firefox containers were developed, however in the absence of a tab groups API, conflicts are inevitable

Apple knows what they owe to open source software: https://opensource.apple.com/releases/

A lot of the core XNU and Darwin code is open source: https://opensource.apple.com/releases/

Uhh...

I think NeXT might've written an HFS Standard reader or something, but they used the Apple code for HFS+ so it ended up as a hybrid.

Mach message passing and objc message passing have no relation. I don’t think xnu contains much if any objc.

Obviously not all of its, but they contribute quite a bit. https://opensource.apple.com/releases/

here is the kernel source (they have branches for each individual macos release with its darwin kernel ver, macos 13 is ver 8792.xx.x for instance): https://github.com/apple-oss-distributions/xnu

Apple does plenty of open source stuff. Safari's browser engine, Swift, libdispatch, the XNU kernel used by iOS and macOS, etc. And macOS is generally packed with open source things, like the default shell, zsh. Also, Metal actually predates Vulkan, so Vulkan was definitely not established when they started focusing on Metal. Yeah, they probably should consider supporting Vulkan now, but it's nothing to do with open source. The main beneficiaries of Apple supporting Vulkan would be people porting closed-source games.
