The "Browser Websocket Client" addon ( https://github.com/abeade/browser-websocket-client ) was automatically disabled. The addons manager says: > This extension is restricted for violating Mozilla’s policies and has been disabled. You can enable it, but this may be risky. However, I cannot find any information about which policies the addon violated or when. If it was logging or modifying data, I want to know to what extent I may be compromised from using the extension. If it was for lack of maintenance, I want to know so I can make an informed decision about whether to keep using it, because the addon was still useful to me and my work as of recently.
