Maybe some kind of key press emulation is needed in such cases?

Thank You Very Much Absolute..This extension has helped me very much by saving a lot of time for me..
This add-on does what it is expected to do. I Will continue to use it.

Tried a few "allow" copy add-on, only this one works.

It works great but I had to disable it because it breaks Facebook. I hope you can fix it.

Great little add-on. 4 stars because once active you have problems with Facebook.

Very simple and efficient when you can't right click.

searching answers for online exam made esay

La mejor de este tipo que he probado.

Love this add-on but recently have been running into an issue with it. With it enabled, video controls don't work. Clicking to raise or lower volume, or clicking on the video timeline don't work. All YouTube videos, and many other sites, too.

It does very well what promised.
Anyway be advised not to change once for ever in about:config
dom.event.contextmenu.enabled to False otherwise you shall have troubles with BigG jscripts.
