:( Good idea yet not working.

Select `https://goo.gl/aESk5L` , nothing appears in right-click context menu.

Firefox Developer Edition 63.0b10 (64bit), Windows 10 1803

Does what it says - and to the other commenter saying it should include an option to show them by default. Well, maybe so - I'm sure the developer will take code commits. Scratch your own itch!!

There should be an option to show always target url without right clicking it

Thanks for a great add-on!

It does expand the URL once you right click and select "Simple URL Extend..".
