It is what i need, but much easy way as hot-keys. Please make it available on right-click on tab. Please update

Since PlainOldFavorites no longer works with FF57+, this is the closest add-on for saving a web link as plain .url. However, it is 1) very clunky in that you can only use a hot-key 2) no context sensitive option 3) saves an image of the page inside a sub-folder etc. Please consider implementing the base functionality of PlainOldFavorites.
