Timeback puts the algorithmic feed on a short leash

Field notes

The extension uses a fixed five-site manifest rather than attempting to become a general-purpose feed blocker. Its visible control model is deliberately small: each site has a list of hideable elements, with one-click restoration and independent pausing. The documented defaults cover 7 YouTube elements, 4 each on Instagram, X, and LinkedIn, and 2 on Reddit. The site also describes pre-paint hiding and six-hour automated checks for markup changes.
