Panorama is Messing up my tab Groups on Restart
So I really like the idea of Panorama, and I tried to use it to divide some sites into related categories. For instance I have a group of Irish News site, a group of news aggregator sites (Google news etc), and then a group of British news sites. This all works fine and dandy, and I can swap between the groups of tabs using Panorama. But everything gets major screwed up when I close firefox and restart it. When I restart firefox the groups of tabs are just all over the place and are completely muddled with each other. If there were 3 groups of tabs in Panorama when I closed FF, the three groups are still there when I re-open FF. But the tabs inside have been completely scattered across the groups. It is very not hot, and makes Panorama completely unusable!
Note: I have set FF to "Show my windows and tabs from last time" in the main settings menu.
Any advice on how I can fix this please??? Thanks!
