Oh yes, I see that now. Mine's grayed and if you haven't set up Sync, I assume yours is, too.

I'm not aware of a built-in way to hide that item. But...

You can apply a custom style rule to right-click context menus to hide individual items. For example:

/* Hide "Send Link to Device" and preceding separator */
#contentAreaContextMenu #context-sendlinktodevice, 
#contentAreaContextMenu #context-sep-sendlinktodevice {
  display: none !important;
}

The most forward-compatible way to do that is to create or edit a userChrome.css file. When you have five minutes, take a look at the steps here: https://support.mozilla.org/questions/1164362#answer-978078

i do not have userChrome.css , only userContent.css Can I edit userContent.css which already has this command

/* about:home */ @-moz-document url(about:home){

#snippetContainer { display:none !important; }

}

Just skip a few lines and put new command?

also want rid of serach google for whatever is highlighted in context menu

How do i remove the word mozilla from top right of home page? see screenshot?

Thanks

You can add new rules below existing ones, yes.

Menus are part of the user interface, so modifying them requires rules in a different file named userChrome.css ("chrome" is the interface bits). Please start a different thread on that.

Try using the Inspector tool to gain information about how to identify that element in your style rule. Or in other words, to identify its CSS selector.

https://developer.mozilla.org/docs/Tools/Page_Inspector

If the element has an id="some_text" you can style it by creating a rule prefacing that id with the hash character:

@-moz-document url(about:home){
    #some_text { display:none !important; }
}

Add code to the userContent.css file.

• http://kb.mozillazine.org/userContent.css

@-moz-document url(about:home){
  #aboutMozilla { display:none!important; }
}

Add code to the userChrome.css file below the default @namespace line.

• http://kb.mozillazine.org/userChrome.css

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */

#context-searchselect {display:none!important;}

• create the chrome folder (lowercase) in the <xxxxxxxx>.default profile folder if this folder doesn't exist
• use a plain text editor like Notepad to create a (new) userChrome.css file in the chrome folder (file name is case sensitive)
• paste the code in the userChrome.css file in the editor window
• make sure that the userChrome.css file starts with the default @namespace line
• make sure that you select "All files" and not "Text files" when you save the file via "Save file as" in the text editor as userChrome.css.
  otherwise Windows may add a hidden .txt file extension and you end up with a not working userChrome.css.txt file

Not working :(

Did this just change in Firefox 56 from "Send Link to Device" to "Send Page to Device"??

/* Hide "Send Page to Device" and preceding separator */
#contentAreaContextMenu #context-sendpagetodevice, 
#contentAreaContextMenu #context-sep-sendpagetodevice {
  display: none !important;
}

Note that the screenshot shows a file in the Firefox program folder.

The userChrome.css file needs to be in the chrome folder in the Firefox profile folder.

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.

• Help -> Troubleshooting Information -> Profile Directory:
  Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder
• http://kb.mozillazine.org/Profile_folder_-_Firefox

Note that the source code shows these context-send context menu items.

#context-sendaudio
#context-sendimage
#context-sendvideo
#context-sendpagetodevice
#context-sendlinktodevice
