User Reviews

User reviews are mixed: many praise it as simple and effective when it works, especially for restoring the old YouTube UI. However, reliability is a major issue, with several reports of it not working and the project appearing outdated. Functionality often seems limited to the home page, and changes to YouTube can break it, occasionally necessitating manual workarounds. Overall, useful but unstable and not actively maintained.

Pros

When active, it works well and reverts YouTube to the classic UI.
Small and simple to use.
Restores the pre-Polymer YouTube design across the site.

Cons

Not reliable; often stops working or breaks after updates.
Not updated for years / appears abandoned.
Currently limited to the YouTube home page and/or specific pages, not full-page coverage.
YouTube changes can break it or ignore the disable_polymer parameter, sometimes requiring manual workarounds.

Recent reviews

Worked well until yesterday, and now polymer is back. Wretched YouTube.

Is Disable Polymer on 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.

Disable Polymer on YouTube requires a few sensitive permissions. Exercise caution before installing.
