The developer of this extension has resigned. Even if it looks like it, this was not an update on April 25, 2024. The proof is visible to everyone, you just have to click on Show all versions. Version 1.3.9 is the final version of this extension and there will be no further updates. As an honest developer, you should be honest enough to say so in the description of this extension. The extension works fine, but for how much longer? After all, there are continuous updates for the Firefox browser. The single star refers to the behavior of the developer and not to the extension itself.
