My Laptop I only use once in a while because I am mostly at my desktop. When I didn't use the laptop for some time, I am logged out of ALL websites. Google, Facebook, Twitter, Instagram, Reddit, eBay, Amazon, several smaller sites EVERYWHERE. It's like I am on a new install. How do I stop that behavior? It's certainly not an issue of the websites because I am logged out consistently everywhere. Why is Firefox deleting the cookies even if they are infinite? My laptop is secured, it has strong passwords and an encrypted harddisk.
