That’s actually much smaller than I expected.

Check out Vimm’s Lair, it has everything you can think of.

I think he was trying to demonstrate for new users that it would redirect them to use the appropriate installer instead of relying on .exe files?

That’s good to know.

Careful with that I think it’s against their TOS to do that due to the large volumes of data video streaming takes.

My issue with keycloak is that the documentation is very poor as a beginner. It and almost any other guides online assume you already know things that you may not so I wasn’t able to get past that hurdle.

Can’t you setup Firefox to remember the last session and reopen the same pages upon relaunch without any user interaction?

I feel like Linux is good for power users or users like your grandfather who are not very tech savvy. The issues arise with users savvy enough to get themselves into trouble but not enough to understand how to fix it or how to do a slightly more advanced task.
