This simple extension adds an IMDb search for any text you highlight to the right-click menu.
If you see a name that you want to look up on IMDb, just highlight the name, right click, and select "Search IMDb for " on the menu.
The search executes in a new tab.
The extension is tiny and takes very little memory. To keep it small, there are no options.
The extension "Right-Click Search IMDbPro" is available if you want to search IMDbPro (requires IMDbPro account). Install both if you want both search options.
