There will be a circle with FBP in the upper right corner of the browser. Clock on that and a box with all sorts of sorting and blocking goodies comes up.

Each little arrow item on the far left (Newsfeed filters) will address different features. They don't all work perfectly, because it is a running battle between the Facebook developers changing code and the owner of this app finding fixes around those changes. Facebook is intolerable with all of the default crap they put in it.

I don't need to know if someone joined a group or shared a memory, I don't want polls from FB, I don't need to know a lot of what other people are doing on their FB accounts.

I hide thinks like games and apps, markeplace, suggested groups, whatever the fuck "pokes" are, and "happening now" stuff. I hide sponsored posts (ads, basically), games, stories, tag and comment suggestions (they will prepopulate the text bar for you - at some point Facebook will do all of the clicking and talking to itself and no humans need to make any choices).

What I do have set is the "deleted friends alert" and the "name change alerts." Those are helpful. I have it set to show all comments, not just what FB things is "relevant." And I use the Text Filter so that people I follow can stay in my list but when they write on certain subjects they won't appear in the feed.

That filter so far has:
Donald Trump
Elon Musk
Trump
Musk
Supreme Court
ICE
RFK jr
Kirk
Epstein
immigration
Bondi

and I add to it every so often. The density of the Trump World crap is too much so if I can thin it out, I do. Save and close when you finish.
