How long do tab groups stay in the browser? The tab groups I create disappear from 'list all tabs' dropdown. I was unaware there was a time limit. Could you let me know if I am doing something wrong here or change the description to include a timeframe. Saying that I can reopen suggests I can always reopen (see help article quoted below). "You can Save and close group, which will save and close the group for you to be able to re-open from the List all tabs tab icon 2 icon on the tab bar (or the Fx137ListAllTabs toolbar icon, if you use vertical tabs). " I have lost a number of groups, which is not ideal. I see two tab groups from last four days but no others. See screenshots. Would love clarification of this, as it is so useful to keep sites in groups for later use. Thnks
