Tabs disappear or move from group to group in Panorama in FF4
Tabs keep moving from one group to another or disappear completely after closing and then reopening firefox.
This did not ever happen while using FF4 Beta or FF4 RC. It started happening after FF4 went live. I'm not sure how many times it happened prior to its discovery.
No add-ons or plug-ins have been added since except one which has now been removed

I have fixed my own problem. It turns out that my sessionstore.js file must have been corrupted. There was a sessionstore.js and a sessionstore1.js file. So I deleted both along with the sessionstore.bak file and then closed down FF4 (with the tabs and groups arranged the way I wanted them), opened it back up and everything was where it was supposed to be. It's been fine ever since.
