User Reviews

Users praise the add-on for blocking autoplay on many sites (notably YouTube and Facebook) and consider it a long-standing, reliable autoplay blocker. However, multiple reviews report serious drawbacks: it interferes with CAPTCHA/authentication systems (Cloudflare and Google reCAPTCHA), causing login/verification issues; its behavior is inconsistent across sites (works sometimes, requires refresh); and some users report it doesn't reliably block YouTube autoplay in Firefox. Overall, it's a powerful tool when it works, but compatibility and maintenance concerns limit its reliability.
Pros
  • Blocks HTML5 autoplay on many sites, improving browsing experience.
  • Works on popular sites like YouTube and Facebook as expected.
  • Historically reliable and well-regarded for years.
Cons
  • Interferes with CAPTCHA and anti-bot systems (Google reCAPTCHA v3 and Cloudflare), causing login/verification failures.
  • Inconsistent behavior across sites: works sometimes, sometimes doesn't; requires refresh or toggling.
  • Doesn't reliably work on YouTube in Firefox for some users.
Recent reviews
Currently causes a Cloudflare confirmation loop on Indeed.com, but works well everywhere else I go.

Some websites ignore Firefox's setting to block video/audio autoplay. This extension magically fixes this issue! Thank you so much Afnan Khan!!

Plugin works most of the time, but really slows down Firefox to the point where I had to uninstall this extension. But, it's not been updated in some time, so it appears to be abandonware.

Is Disable HTML5 Autoplay 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 HTML5 Autoplay requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
