Was having the same problem that started out of the blue about a week ago. Every time I tried to add images to my posts Firefox just closed with no warning. I hadn’t done any updates or new installs. I was stumped. I even tried to reinstall WP in case a file was corrupt. Still same problem. I disabled Google Gears and all in now working. ?? The whole thing is just weird, because I’ve had Gears installed and running for months.
Thank you maikelneris for sharing this solution – you’re my hero ??
