Hi there! I'm really sorry to hear that. Firefox's new security rules (Manifest V3) completely block extensions by default until they are manually enabled.

I have just released an update to fix this! Please update the extension, open its popup from your browser toolbar, and click the new "Let's do it" button. It will automatically request the necessary permissions.

Once enabled, everything should work perfectly. Thank you for your patience, and please let me know if it works for you now.
