- (2024-09-08) Andres Herrera: It works and is simple! I had a problem with an old web app that doesn't work when the browser is in a language other than Spanish, but I didn't know it. I used ChatGPT, and with it, I figured it out. GPT suggested I install an extension to modify the Accept-Language in request headers, and this is the one I used. Now, the web app works as expected.

- (2023-04-11) Prashant Negi: Many YouTube videos show "An error occurred. Please try again later. (Playback ID: ___)", then i have to refresh the page again for the video to play. This is solved by disabling the last 4 YT headers. Please include the ability to block certain sites.

- (2021-10-01) Андрей Кузнецов: Convenient and functional extension. My only wish: Enable the ability to have multiple data (rules) profiles, at least so that the old data is not erased during import.
