In-depth safety analysis
This extension requests activeTab, storage, and scripting permissions. Together, these allow it to inject a script into the current tab when you activate the extension, and to save your speed preferences locally. For a video speed controller, this scope is normal and expected — it needs to modify the playback rate of video elements on the page you are viewing.
As a general browser utility, the main category-typical consideration is that any extension with scripting access can read and alter page content. A careful user should only install such tools from trusted sources and be aware that an abandoned extension might not receive security patches if browser APIs change or vulnerabilities are discovered. The activeTab permission limits access to tabs you intentionally interact with, which is a safer design than broad host permissions.
The strongest dimension in the fact sheet is Data & Privacy, where the developer has declared that data is not sold or used for unrelated purposes. The weakest is Maintenance & Ownership, reflected in a low score and a last update date of November 2023. This suggests the extension may not be actively maintained, which could affect long-term reliability and security responsiveness.
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.
