Reddit Domain Blocker

Loading your list…

When a post matches

How a blocked post should disappear from the feed.

Collapse to one line — leaves a "Hidden: domain" row you can expand Hide completely — the post vanishes with no trace

One domain per line, or separated by commas. Full URLs are fine — they get trimmed down.

Saves your blocked domains as a JSON file you can keep or move to another computer.

Reads a file exported from this extension. Domains already on your list are skipped.

When the file loads Add to my list — keeps everything you block today Replace my list — discards your current domains and preferences
