Hey, sorry for the late response. Make sure to first download and install the Native App, and then download the Firefox Extension. If it still doesn't work after that you might have to restart Firefox once for it to work, but it usually doesn't need to.
So if you still have the Extension installed, 1. Uninstall the Extension 2. Download & Install the Native App from Github 3. Download the Firefox Extension 4. (maybe restart Firefox)
