works for me 👍🏻 Without Addon:

Disable right-click menu manipulation via JavaScript (disabled)
dom.event.contextmenu.enabled false

Works marvelously for me. :) I habitually right-click to go back a page when browsing, so it's infuriating when web designers override it for no good reason. I also appreciate that the code's on GitHub for review. Thanks so much for writing and publishing this!

Tested on Aug 13, 2021.
I wanted to download a video from a private facebook group.
Steps:
1. Change the www in the URL to 'm'.
2. Click play on the video.
3. Click Allow right-click extension.
4. Right click on the video and save the video as.
Worked fine.

Very good addon to keep control over the context menu on patronizing websites, although it is better to avoid such websites anyway.

This extension is really good.( Sorry for my bad english)

Very simple, but oh so necessary.

great extension for some reason i cant right click in my browser but now that i installed the extension i can right click on pages where i never been able too , i never write reviews but i thought this extension deserves my review and privilege of doing so ,, good job guys ,,

It works on Facebook! Perfect! Facebook just today disabled the right click menu for saving images. This overrode their attempted *&%$#@

Yes, just what I needed. Thank you very much for creating this <3

Just to let people know, just go to about:config and change dom.event.contextmenu.enabled to False and websites can No Longer Block Right Click.

i would hope that the extension developer doesn't delete this comment as i still gave you 5 stars, plus an extension like this should be for people who is scared to mess with anything in about:config or just doesn't know about it.

This right click extension works better then the other force right click extensions in Firefox, you just have to click on the icon first to get it to work, sometimes twice, this extension it the only one i have found that works on video, giving you the ability to force play and pause, which is the main reason i use this extension. I use it to force play on sites that want to play the million pop-up game before it actually allows you to watch the video. Thanks so much for this extension !!!!!! You made my life easier

Working, Great and ease to use add on.
