A must-have extension for every install of firefox I have, would highly recommend using this. Web security matters.

Something weird started happening recently, the extension just hangs and I'm unable to open websites. Debug info of the addon repeats this line

Uncaught (in promise) Error: Could not establish connection. Receiving end does not exist.
send moz-extension://0bdccd93-3bcd-40de-8763-8dcb82ab7603/nscl/common/Messages.js:66

The only way to fix this is to restart firefox. Disabling and enabling extension doesn't work (I could disable noscript and websites would start working, but then I'd have lots of scrips left unblocked).

I love this. I can control what JS does granularity. Thank you so much for creating it. I love to help if you work with the community.

Like the reviewer VoxPop I too began to have issues with this extension - which I have used for several years - quite recently. It appears to be related to Firefox Sync as whitelisted domains disappear after I have used another PC upon returning to my main machine.

It has been an excellent, if occasionally labour intensive, addition to my online security but as of writing it frustrates as much as it protects.

Thanks for providing me this
