The extension is published now, so the install section leads with the store link and keeps the temporary load as the way to run this checkout.
Outlier Badge
A Firefox extension that puts an outlier score on the corner of every YouTube thumbnail. Score = the video's views divided by the median views of its channel's last N videos. The median is a deliberate choice: a single viral video would drag a mean upward and make everything else on that channel look like it never outperformed. Shorts are scored against the channel's Shorts, regular videos against regular videos, and live streams enter no pool at all. The watch page also gets a panel with the score's details and the channel's recent view distribution.
No server, no API key, no account: the extension calls YouTube's own internal
(InnerTube) endpoint from inside youtube.com, without session credentials. One
request per channel, cached in storage.local for 24 hours by default, and cards
are only processed once they scroll into view.
Installing
Get it from addons.mozilla.org.
To run this checkout instead: about:debugging#/runtime/this-firefox → Load
Temporary Add-on → the manifest.json here, which disappears when Firefox
closes.
Using it
The toolbar icon opens the settings: turn badges off, skip Shorts, pick the baseline size (last 15/30/60/90 videos), hide scores below a threshold, set the cache lifetime, choose the interface language, and clear the cache. The same popup reports how many cards were scanned and scored in that tab, which is where you look first when a badge fails to appear. The interface is available in English and Turkish, following the browser's language by default.
To exercise the parsing and scoring logic without opening a browser, run
node test/check.js (it makes one real channel call too).
Known limits
- YouTube hands out rounded view counts ("1.2M views"), so the score is an approximate ratio rather than an exact one.
- Videos under 7 days old have not gathered their views yet and score lower than they deserve. The dot next to the badge marks them.
- The baseline is the channel's last N videos, not its whole history. On a growing channel an old video scores higher than it should.
- Members-only videos never expose their view counts, so they neither join a baseline nor get a score.
- With fewer than 3 videos left in the pool no score is computed and no badge appears.
- InnerTube is an unofficial interface. If YouTube renames its fields the badges disappear; the page itself keeps working.
