In Firefox, and Firefox only, in every version for the last several months, I have found it impossible to get Firefox to allow websites to "remember this device", even when I check that option. Every day I log in to a website, for example Tmobile, and I have to get a code emailed to me. I check "remember this device so you won't need a code next time", but the next time I log in, the same thing happens. Over and over with many sites. This does not happen with any other browser, except Firefox. How do I get Firefox to allow me to save my info? I really don't want to use Chrome, Safari, Brave, or Edge, but I do not have this problem with any of them. Only Firefox. And yes, I've checked my settings, and everything I can see says Firefox should be saving this info.
