Hi Mozilla, Yes I did try in Safe mode and that worked until logging off and then restarting FireFox. Since the most recent FireFox update Safe Mode no longer works. I can still login to the site and perform some rudimentary tasks but when I want to edit/view a payment I get the error message as posted. If I use my Tablet to login I have no problem although the Tablet uses Chrome and not Firefox. I can try the tablet with FireFox and report back. Is their a log file or setting list that I can send that will help. Regards, Greg
