Block A/B Testing (YouTube) Firefox

Block A/B Testing (YouTube)

Remembers the first title you see for each YouTube video on the watch page, Shorts, and lists and always shows that title.

Features & Capabilities

YouTube sometimes shows different titles and thumbnails for the same video (for example A/B tests). This add-on remembers the first you see for each video and keeps showing these title and thumbnail on the player and in list-style pages (home, subscriptions, search, related videos, and similar).

How it works: The first time a title/thumbnail appears for a video, it is saved locally in your browser. On later visits, these same are shown again for that video ID. Updates run after navigation (including YouTube’s in-page history changes), with short retries so metadata can load—there is no aggressive continuous polling of the whole page.

Scope: The add-on only runs on youtube.com. It does not run on other sites.

Privacy: No accounts, no analytics, and no requests to our servers. Pinned titles are stored only in the browser’s extension storage on your device. See the privacy policy link on this listing for details.

Requirements: Firefox 140 or newer (desktop). Firefox for Android 142 or newer, where applicable.

Is Block A/B Testing (YouTube) Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Block A/B Testing (YouTube) requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
