In-depth safety analysis
This extension requests only the "storage" permission, which allows it to save your preferences (such as whether thumbnails are hidden) locally in your browser. It does not request access to your browsing history, tabs, or the content of any web pages. For a general browser extension that modifies the appearance of a single website, this is a minimal and expected permission scope.
Users of appearance-modifying extensions should be aware that even simple tools can sometimes break if the target website updates its layout. More broadly, extensions in this category can occasionally be bought or hijacked and repurposed to inject ads or tracking code in future updates. A careful user might periodically check that the extension's behavior hasn't changed unexpectedly after an update.
This extension scores well on Data & Privacy and Permissions & Access, with a perfect score in both dimensions. The developer has declared that data is not sold or used for unrelated purposes. The weakest dimension is Publisher & Identity, which typically reflects limited publicly available information about the developer or their track record. Community reputation is strong, with a high rating across a substantial user base.
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 Hide YouTube Thumbnails?
- Publisher Adam Jones
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.
