In-depth safety analysis
This extension requests only the "storage" permission, which allows it to save your settings (like preferred playback speed) locally within your browser. This is an extremely limited permission set for a video speed controller and is completely expected for this category; it does not grant the ability to read or modify data on any website you visit.
Even with a perfect permissions score, users should understand that extensions in this category typically inject scripts or styles into pages to function. While Video Speed Controller declares no host permissions, it operates by intercepting page content. A careful user should know that any extension that modifies page behavior could theoretically be targeted by supply-chain attacks or become incompatible with streaming platform updates.
The strongest dimension in the fact sheet is Maintenance & Ownership, indicating the extension is well-maintained and has a clear ownership record. The weakest is Publisher & Identity, which may reflect the individual developer's limited publicly verifiable company footprint, though this is common for solo open-source developers and does not indicate a security issue by itself.
AI-assisted analysis of the documented signals above (permissions, store data, privacy practices) — explains what they mean and the risks typical for this category. Not a hands-on test.

Who's Behind Video Speed Controller?
- Publisher igrigorik
Public records identify the publisher, but no individual founders or a separate registered company are named — which is what holds the Publisher & Identity score back. Less public information about who operates an extension means less you can verify about their long-term accountability.
