I normally put the computer to sleep at night, rather than powering down (although I do that periodically). After waking the computer, and clicking Firefox open, the browser loads with the two or three tabs I last had open, and within the minute closes. There's no warning or pop-up window saying what happened. I open it again, and within the minute it closes again. This happens four times. On the fifth try, Firefox opens without the previous tabs and with just one "New Tab" showing. After that it's fine. Also, it doesn't happen if I wake the computer and let it sit for a while before sitting down. This is an oddity that I can live with. I'm just curious about what's going on. Thanks, Ed LeRoy
