Hi This problem still occurs, this time it took about 3 days before it reoccurred. I'm having a problem that appears to be linked to syncing. I can clear it with "Refresh Firefox...", but then it will come back in about 2-3 days. Deleting my profile didn't help. The original problem description can be found at the link: https://support.mozilla.org/en-US/questions/1355876?utm_campaign=questions-solved&utm_source=notification&utm_medium=email#answer-1459234 Are there logs I can review or collect? Thanks. Roe
