Save Tabs to HTML is a Firefox extension designed for users who need to manage their open tabs efficiently. This subscription-based addon generates an HTML file that includes the titles and URLs of all open tabs across all browser windows, along with the browser user agent and the timestamp for when the file was created. This functionality provides a convenient way to preserve a browsing session without the need to bookmark each page individually.

Unlike other similar addons that export tab information as plain text, Save Tabs to HTML offers an HTML format, allowing users to easily click on the URLs to re-open them in their browser later. It is important to note that this addon excludes incognito tabs and does not store the actual webpage content, focusing solely on saving the essential information for later access.
