Tabsets is a free Chrome extension developed by Bernhard Hofmann. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory.

Tabsets allows users to store sets of tabs for later viewing. With this extension, you can keep all the tabs you have open in a set and open them all again later, even on another device if you have synchronization enabled in Google Chrome.

The extension provides a list that shows when each set of tabs, or "tabset," was created, along with the number of tabs in each set. This feature is particularly useful for organizing various research projects or work tasks into sets of tabs that can be restored with just a click. Each tabset can be expanded to view the individual tabs within it, allowing for easy removal of tabs one at a time. Additionally, users have the option to rename tabsets, add the current tab to a tabset, and import or export tabsets as plain text to share with others.

It is important to note that Tabsets requires permissions to retrieve the title of each tab, but it does not read the contents of web pages. The source code of the extension is open source on GitHub for verification purposes.

Tabsets has a version history that demonstrates regular updates and improvements. The latest version, 1.23, introduced the ability to export all tabsets in one action and auto-detection of import to handle single or multiple tabsets. Other notable updates include the option to sort tabsets by name or creation time, saving tabsets with the local date and time of creation, reordering tabs within each tabset, and preventing total data loss in the event of storage errors.

Overall, Tabsets is a valuable extension for users who frequently work with multiple tabs and need an efficient way to organize and restore them. Its user-friendly interface and useful features make it a convenient tool for managing tabsets across devices.
