右键先生-360搜索 is a Chrome extension developed by Browser Helper. It is a free add-on that focuses on providing 360 search functionality directly from the right-click menu. Unlike other right-click extensions that offer a variety of options, this extension simplifies the process by placing the search button directly in the top-level menu, making it more convenient for users who frequently use 360 search.

The main feature of this extension is the addition of a 360 text search option in the right-click menu. It utilizes the Event Pages development mode, which ensures that the extension doesn't consume memory when not in use. Memory is only allocated when the search button is clicked in the right-click menu.

One advantage of this extension is that it provides a better user experience for frequent 360 search users. Instead of burying the search button in secondary or tertiary menus like other comprehensive right-click extensions, this extension places the search button directly in the top-level menu for quick and easy access.

Currently, the extension does not include image search functionality as the developer believes that the current 360 image search feature is not optimal.

Overall, 右键先生-360搜索 is a useful Chrome extension for users who frequently use 360 search and want a more efficient way to access it directly from the right-click menu.
