Hi   ! Could you be a bit more specific, please  ?

You say : "When you right-click, a context menu appears"

When you right-click what   ? And what context menu appears  ?

HI. when i right-click mouse button uppear that menu with last item "make screenshot" it was added in last mozilla update. Can i remove this item or push it to the top of menu ?

Type about:customizing<enter> in the address bar. In the new window, look for the icon. When you find it, hold down the left button on it, and move it to where you want it to be. You can move any of the icons you want from here, but; some icons are locked in place.

There is also a Restore Defaults button at the bottom middle.

Note: about:customizing is no longer present in Firefox 47+ releases.

• Press Alt or F10 to bring up the toolbar.
  Then View > Toolbars > Customize.
• Right-click on a blank spot in the toolbar and
  select Customize.

When you click on an empty space - doesn't that context menu disappear  ? I'm on Windows 10 and I have to press the three bar key on my keyboard to get that context menu - don't have a mouse, but imagine that right-click will bring that context menu up as well. Clicking on an empty space makes the context menu disappear for me ....

problem isnt of uppearing/disappering menu, problem is in "make screenshot" item, i want to remove it from context menu or move up.

Hi, try this: Type about:config into the address bar, press Enter, accept the warning, scroll down to extensions.screenshots.disabled and double click on it to change 'Value' from False to True. Restart Firefox afterwards.

Ahh,   I finally get what you mean ..... To remove items from a context menu, I think you will need to suppress their display by making CSS entries for them in your userChrome.css file, and I don't know how to do that.

But maybe this you'd like to try this add-on : https://addons.mozilla.org/en-US/firefox/addon/s3menu-wizard/

about:config works great to remove take a screenshot from context menu, thanks, Scribe!

Now, how can I remove "send tab to a device" from the context menu as well? I tried looking at about:config for tab, send, and device, but didn't see anything that looked relevant (though there's a lot under 'tab', so I might have missed it).
