This is a migration of the excellent XUL/XPCOM bookmark current tab set Firefox extension by Jake Kasprzak to the Webextension model. The extension stopped working with the release of Firefox 57 (Quantum) and the original extension has not yet been ported.
I use the extension to automatically bookmark open tabs when a window closes. This helps preserve a rich browser history over long periods of time.
The migration work is occuring on the webex branch.
The current version works but does not have configuration settings. My preferred defaults are hard coded.
