OK, I am a heavy user of tab groups in Firefox (glad to get off Chrome once this was available). Unfortunately, Bookmark All Tabs only saves the open tabs in my Firefox window. It Does Not save anything inside a tab group that isn't opened - AND it doesn't save any of the tab group structure - ex. the group, what is inside it, etc. IS there some way to properly save all the tab information (groups and tabs inside those groups) in Firefox? There is in Chrome by the way. IF there isn't, has someone out there produced an extension to do this?? Seems like a big oversight in the intro of tab groups if there is really no way to do this... I do the Bookmark All Tabs for backup and have needed it many times in my Chrome past usage. Thanks in advance
