Firefox has suddenly made all of my home page recommendations really trashy UK based tabloid junk from the same half dozen or so sources.

I don't know why Firefox made my homepage so messy, with so many junk suggestions. It used to be a lot of thoughtful / interesting stuff about science / nature / health / politics / philosophy think-pieces and now it is all just "(unkown celebrity name) clashes with (council) over (something I don't care about)" or "(american president) shocks defense community with late night Truth Social Screed (BROUGHT TO YOU BY TABLOID PAYWALL)." Everything is suddenly UK only, and it is all from the Metro, the Mirror, the Independent or Sky News. I never, ever read any of that. I am sometimes in the UK, but not now. And my VPN is never set there. I don't want to block whole themes - Health? I might be interested in some of that, but I don't need ten stories from the UK health sector gumming up my feed every day. Food? I used to occasionally get good recipes on the home page, but now it's a whole section of choco-banoffie protein smoothies and fried chicken, which I would never, ever click on or prepare. Money? All of these things have potentially interesting options, so I don't want to block them, but I'm definitely not interested in getting loads more of any of it. Is there any way to go back to region neutral 'this is interesting' stuff? I find the current home page to be really unpleasant.
