A way to make Facebook more usable is to always
view it in your browser with an app called F.B Purity – the main thing this can do is turn off all the crap (no more side bars or notifications)

I’ve used FBP for years and regard Facebook as totally unusable without it because of all the crap they put in there.

The other important thing to do is to switch to "feeds" so you see everything in chronological order, and not in Facebook's bullshit algorithm feed.
