Browser extension adding a button that automatically closes tabs whose URL match specific patterns

Originally built as a way for tab hoarders like me to quickly close work-related tabs that have accumulated during the week before going on PTO or week-end.

Example usage:

• Open the add-on preferences page, and add a pattern for *://github.com/*.
• Click the button, and all tabs from Github should automatically be closed.

Pinned tabs are excluded, and patterns should be synchronized across multiple devices.
