Hi everyone. Basically when the browser is (I think) idle while watching YouTube, FF is constantly backing up (the timestamp in the backup file name keeps getting updated). From the settings page I thought it once every 24 hours. I noticed from higher than normal CPU usage impacting FF and the Windows search indexer. Which reverted to normal once I disabled the backup. I checked the about config: * browser.backup.scheduled.minimum-time-between-backups-seconds Is set to 24 hours (86400 seconds) But I also noticed: * browser.backup.scheduled.idle-threshold-seconds Is set to 15 seconds(!). Is that what I think it is? Back up whenever there's a 15 sec idle window, regardless of the minimum? Can I safely make that 86400 seconds too, or does it do something else entirely? Many thanks in advance.
