Background: in Firefox, I can edit user.js and disable specific media codecs, which makes blocking video much easier. Chrome doesn’t provide an equivalent user.js/codec-disable path, so this extension uses MV3 static declarativeNetRequest rules to block common video delivery requests.
No analytics/telemetry. No remote code. It blocks many common video requests, but it doesn’t claim perfect coverage on every site/player. I’d love feedback on false positives/negatives and breakage cases.
