ContextSearch web-ext

The most powerful, most complete search enhancement for Firefox

This Add-on was written as a Firefox 57+ web-extensions compatible replacement for Ben Basson's popular Context Search Add-on but has grown into much more.

• Import your currently installed search engines
• Access search engines from the Context Menu
• Manage search engines using subfolders and separators
• Access search engines from a popup menu (QuickMenu)
• Compatible with all search engines using POST or GET requests
• International character-set support
• Reverse-image search
• Site search
• Add new search engines simply with a right-click
• Custom API to build and install custom OpenSearch engines to FIrefox Search Toolbar
• Edit search engine parameters and icons
• Access bookmarklets from the context menu and quick menu
• Highlight search terms
• Lite and Dark themes
• Use custom CSS for menus

* Linux and MacOS X users may need to set the option ui.context_menus.after_mouseup to true in about:config for mouse actions to work properly
