I could've sworn firefox had an "all tabs" preview button that looked like 4 blocks in a grid, before the Australis era. Can't find any pictures/video footage of it in action however. Best I could find is: https://www.askvg.com/how-to-enable-ie-like-quick-tabs-feature-all-tabs-previews-in-mozilla-firefox/ https://www.askvg.com/how-to-enable-ie-like-quick-tabs-featu... But I'm not sure if this landed, or if it ended up functioning differently.
