Could you release a new version which enables it on local files? Not only on http(s)://

I use its userscript version which work perfectly on Waterfox 56.5

It works on websites that doesn't allow you to right click on it, this is what I've been searching for. Thank you!

It always work but it you still have to manually click it

I give it 4 stars because I found out that this add-on interferes with Facebook. It won't let me post, comment or respond to messages. What I did: I restarted Firefox with all add-ons disabled and I was able to post, comment etc. until I reenabled this extension. So, yes it's working but I have to disable it when I'm on Facebook.
