Thank you! Very good, useful smaller extension! In my essentials list. Yes, I know of other 'discard' extensions. I've settled on 'Total Suspender' for now. 'Auto Tab Discard' is good but has some annoyances I can't stand anymore. I should communicate/feedback with that great developer and tell about them. Godspeed! PS Shortcut feature is essential too!

sometimes discarded tabs addresses overlap i.e. tab (www.google.com) tab b (www.wiki.org) after a while the tab a is (google.com) and tab b is (google.com)

This is simple addons to discard tab with shortcut ability, great! Thanks
