Is Video Speed Control Safe? — Extension Safety Profile

This extension asks for the storage, activeTab, and scripting permissions, along with host access to *://*.youtube.com/*. In practice, this means it can remember your speed settings across browsing sessions, run its speed-control code on the currently active tab when you interact with its toolbar icon, and specifically inject scripts into YouTube pages to adjust video playback speed. For a tool whose sole purpose is controlling video speed, this permission set is minimal and expected—it does not request broad access to all websites you visit.

As a general browser extension, the main safety considerations are typical of the category. Even well-rated extensions can change ownership and become vectors for unwanted ads or data collection after an update. A careful user should periodically check if the extension's permissions have changed, especially if it starts requesting access to additional sites. Because this extension interacts with YouTube page content, it is important to note that YouTube occasionally updates its site, which can break extensions and require prompt developer maintenance to avoid security gaps.
