Windows links are here. As for android, you’re right, it is not maintained anymore; the most similar still-maintained browser I could find is Cromite, but I’ve never used it before so I can’t comment on it.

Whichever works best for you. I would recommend Wayland to anyone, but if you run into any problems with it (either bugs with your compositor or protocol limitations), then just use X11.

foot is great. Simple, fast, and customisable enough for my needs.

Infinity was one of the best mobile Reddit apps I’ve ever used. Now the only thing keeping me on Reddit still is the RES extension. When that will eventually stop working too or Reddit decides to get rid of old Reddit, I’ll be deleting my account.

Luckily, there is an Infinity fork for Lemmy.

Rather, use un-googled chromium. Brave is kind of bloated with all of the extra “features” they have.
