Search Multi Tabs is a subscription-based Firefox extension designed to enhance the browsing experience by allowing users to search through open tabs effectively. This tool enables users to search for web page titles and URLs by specific keywords, generating a clickable list that highlights relevant matches with color-coded context. It also features quick navigation via y-position and supports additional tab operations such as deleting or reloading tabs, while displaying favicons for better identification.

The extension is limited to the current window and may not function correctly on certain pages, such as Google results. Users can utilize jumpy access and initiate Google searches with a simple keyboard shortcut (Alt+Enter). However, there are some known limitations, including issues with regular expression searches and specific page types that may not be searchable. Overall, Search Multi Tabs provides a focused and efficient way to manage and search through multiple tabs in Firefox.
