I would like to have a special URL in my FF context menu so that when I select some text and right click on it, I can have an option to add that text into a specific URL, as in [https://somesite.com/?MySelectedText](https://somesite.com/?MySelectedText) and go to that URL… but I cannot seem to figure out how to do this. Is this possible?

Yes, it is possible. Take a look at LEO Dictionaries to see how it’s done…

Yeah, you can do it using the window.getSelection() function from a content script. I’ve done something similar in [my add-on](https://github.com/WesleyBranton/Outlook.com-mailto). I did some messaging to the background script, but I don’t think that’s necessary. To be honest, it’s been so long, I can’t remember off the top of my head why I did it that way anyway.
