First of all, check the following: # Click the menu button and select ''Settings''. # Select the ''Privacy & Security'' panel. # In the '''History''' section make sure that the '''Firefox will''' drop-down menu is set to either ''Remember history'' or ''Use custom settings for history''. #* If '''Firefox will''' is set to ''Use custom settings for history'', then make sure that '''Always use Private Browsing mode''' is '''not''' checked. #* If '''Firefox will''' is set to ''Use custom settings for history'' and '''Clear history when Firefox closes''' is checked, then click the Settings button and make sure that '''Browsing & download history''' is '''not''' checked. # Close the Settings page. Any changes you've made will automatically be saved. Also make sure you close Firefox by selecting '''Exit''' in the menu, not just by pressing the system cross button (especially if you've opened several windows). Please reach out if that does not help (and even if it does — we'll be glad to hear you're fine 🙂).
