Selection URL Templates от cfifopi

Selection Context Placeholder lets you right-click selected (or copied) text and open it in a saved URL template, replacing a {selection} placeholder with the text and opening the result in a new tab.

You can save and reuse multiple templates — each shows up as its own context-menu item (e.g. a search engine, dictionary, or translator).

Add new URLs on the fly, fall back to clipboard text when nothing is selected, and remove or clear saved templates from a sub-menu.
Templates persist in local storage.
