How to remove the option "Set as default background..." from the right-click menu on a picture, for all users.
Hi! I would like to know if there is any possibility to remove the option "Set as default background..." from the right-click menu on a picture, for all users. I know that's possible to edit userContent.css or userChrome.css, but this concerns only a profile at a time and being in a domain, I would like to set this for all people using Firefox. Can it be possible to edit a mozilla.cfg file to get the same result?
Thank you in advance for help and tips.

Thank you! I'll check that quickly and let you know if it'll work as I want.
AFAIK then there is no way to do that system wide. You can only do that via userChrome.css or an extension like the Menu Editor per profile .You can install extensions globally, but the user will have to enable them anyway. That is not required for userChrome.css code.
