I definitely share the frustration with Firefox refusing to work if it detects that it was updated, and just showing the "Please restart Firefox" page. AFAIK that's a recent addition, and done on purpose, so not a bug. But definitely not the best user experience. I haven't had a problem restarting Firefox and having all my tabs appearing again. Maybe something is corrupted in your profile? I also haven't found that to be Mozilla's attitude. Luckily a lot of things are configurable in about:config
