Facebook Reels appear in the home feed, in the sidebar, between Marketplace listings, and as a dedicated tab. They are designed to capture attention and extend session time — which works against anyone trying to use Facebook for a specific purpose.
If you open Facebook to check a Marketplace listing, reply to a Group post, or send a message, Reels can turn that short session into thirty minutes of unplanned scrolling. The problem is not willpower. It is that the surface is built to redirect your attention.
A browser extension can intercept that redirect before it happens.
