Search All Tabs is a Firefox extension designed to enhance your browsing experience by simplifying the search process across multiple open tabs. This tool functions as a powerful content search engine, enabling users to locate relevant tabs quickly through intuitive search operators such as 'AND' and 'OR'. It supports indexing of local files and can parse content in approximately 30 languages, providing a snippet preview for each matching result. Users can directly activate the desired tab from the search results, streamlining their workflow significantly.

In addition to its robust search capabilities, Search All Tabs offers several convenient features, including the ability to copy all URLs to the clipboard, group matched tabs into a new window, and navigate using keyboard controls. The extension also includes a dark theme option, a sidebar view for easy access, and deep search functionality that displays multiple snippets for a single tab. This subscription-based tool operates offline, storing its indexing database in the browser memory without requiring server-side interaction.
