Although you can manually sort your feed chronologically (every time you go to Facebook), you can’t set this as the default.
If you use often Facebook from a web browser on your computer, then I highly recommend installing the F. B. Purity extension to take control of your Facebook experience.
The setting I set first is “News Sort : Most Recent” because I hate missing posts by my friends and family when Facebook decides they shouldn’t be featured on the news stream. This way I can view Facebook posts as they happen.
There are lots of other settings, and each has an explanation if you hover your mouse over it. I probably would have deleted my Facebook account by now if it weren’t for this browser extension. I have removed the Facebook app from my phone because Facebook gives so little control over my experience.
It also helps keep me in the moment when I’m out and about. I take photos, but I don’t feel the need to post them right away. When I’m back home, I can relive the fun from the day and post my favorite photos. If I run across some news I want to post, I have to wait until I have time to be on my computer, so I often skip posting things that are just not that important.
