Hi, Ever since I got my new laptop (changed from windows to mac), I have to sign in to sync my firefox account every time I close firefox and reopen it. I've already changed the settings to what I've found on this support form below and rebooted my laptop, but it doesn't work and I have to keep signing in. What else can I do? Type about:preferences#privacy<enter> in the address bar. The button next to History, select Use Custom Settings. At the bottom of the page, turn on Clear History When Firefox Closes. At the far right, press the Settings button. Turn on ONLY Cache and Form And Search History leaving the others off.
