- The developer has a website (fakefiller.com), which adds some legitimacy.

- The rating is decent (4.4 out of 5), suggesting that many users find the extension useful.

Concerns:

- The "contextMenus" permission allows the extension to add items to the context menu, which could be used for malicious purposes.

- The "activeTab" permission grants access to the active tab, potentially exposing sensitive information.

- The "storage" permission allows the extension to store data locally, which could be a privacy concern if the data is not properly secured.

Recommendations:

- Exercise caution when using this extension, as it has broad permissions and the ability to inject scripts into any website.

- Consider running the extension in a separate Chrome profile or a sandboxed environment to mitigate potential risks.

- Review the extension's privacy policy and terms of service to understand how your data is being handled.
