> Thunderbird has prevented this site from installing an unverified addon. That is a strange issue we have seen lately. Could you answer the following questions: * Which operating system are you using? Windows, Mac, or Linux? Which version? If Linux, which distribution do you use? * Could you please go to Thunderbird | Preferences | General, scroll to the very bottom, click on the "Config editor" button, search for "signature" and tell us which value the setting xpinstall.signatures.required has? Is it true or false? Is it bold or not bold? * How did you install Thunderbird 91? Did you manually download it from https://thunderbird.net ? Or has your installation been updated automatically? If so, by which method (for example by a 3rd party updater like Advanced System Care for Windows, or by the package manager of your Linux distribution)? * If you download Thunderbird 91 directly from thunderbird.net and use that version, does the error remain?
