How curious!

I don't have uMatrix or other ad blocker installed.

I turned off all "Enhanced Tracking Protection" and still see nothing in Firefox.

I don't know what you mean by "by a shitty corporation for shitty ends ... sites that benefit me". It's run by the regional council (https://en.wikipedia.org/wiki/V%C3%A4stra_G%C3%B6taland_Regi...), which is the political organization responsible for the area's public healthcare system. The page lists available COVID vaccination appointments, which benefits me as I was looking to get a booster shot and wanted to know where to go.

I'm sorry, I should have made clear I was referring to the Adobe site :/ Which, to be fair, I didn't attempt to actually use, it's just that disabling uMatrix made the message that it doesn't work with Firefox go away, but I didn't attempt to use it further.

Ahh. That was the one where it actually does work, if I change the User-Agent.
