Unfortunately, I can't tell you anything different that I've done that has led to this problem. Same sites, same habits. At any rate, I always leave FF running. I'm using Windows Vista, and all I do is close the lid on my laptop, it shuts everything down into Sleep Mode. I come back to it, *boom* everything comes back to life. Recently however, after closing and reopening the lid, FF tells me that it has gone into Offline Mode. I haven't found anything in the Tools/Options to fix the problem, so I have to close and restart. Granted, this isn't a major problem, but it's an annoyance. Any ideas of what has happened and how to fix it from going to Offline Mode? Thanks much.
