I removed the FB and Messenger apps from my phone about 2 weeks ago, and I've mostly managed to not open it on my desktop until after 6PM, which has drastically reduced my usage. What finally did it for me was trying to turn off notifications for messenger and realizing there is apparently no way to really do this. You can "mute" them for up to 24 hours but in 5 minutes I couldn't find a way to turn them off permanently. Whether it is possible or not is besides the point. It's an obvious feature and should be easily accessible. I decided to start actively avoiding software that doesn't respect my agency. I'm moving to open source where possible and paid products where not. I'm sick of software designed for engagement rather than user experience.
I use this and love it because I still communicate with a lot of people via Messenger. I'd delete my FB except I've got a ton of logins to other apps that use it, unfortunately. This blocks the news feed completely.
Chrome only (recently switched to Firefox). But it looks awesome. It's incredible to me how effective the post at the top of the timeline tends to be. They know exactly how to suck you into scrolling.
Facebook forces you to download the app to use Messenger when on an Android device (possibly others). A third party app is required to avoid that ridiculousness.
