Tab Vault is a Firefox extension designed to streamline the management of open tabs and URLs. It offers key features such as the ability to copy URLs from all open tabs to your clipboard, allowing for quick sharing and organization. Users can also save these copied URLs into manageable lists, enabling easy access and better organization for frequent browsing needs. With a single click, you can open all URLs in your saved lists in new tabs, enhancing productivity and workflow.

A noteworthy addition is the new local and synchronized storage feature, which allows users to choose between local storage and synchronization across multiple Firefox instances. This flexibility supports up to 100 KB for synchronized storage and 5 MB for local storage. Furthermore, Tab Vault offers customization options, including three themes and adjustable usage settings, ensuring an optimal user experience tailored to individual preferences.
