There are a few places that you may need to check in the Firefox settings to get allow Firefox to log you in automatically. That's done primarily with something called "cookies", which can sometimes be blocked or erased depending on your settings. First, you'll want to check your [[Enhanced Tracking Protection in Firefox for desktop|Enhanced Tracking Protection settings in Firefox]]. If you are using anything other than '''Standard''', Firefox may be blocking cookies. There is a '''Manage exceptions...''' button there where you can view the list of exceptions. Then, if you scroll down to the '''Cookies and Site Data''' section, there's also a '''Manage Permissions''' button there. That will provide you a list of websites that have special permissions or have been blocked. You can try removing the website(s) in question from the list if they are blocked or you can also try adding an allow permission for the website(s). Finally, you should check the '''History''' section of the settings. If you have set Firefox to '''Never remember history''', it's likely that your cookies are not being saved. If you have the '''Use custom settings for history''' option selected along with the '''Clear history when Firefox closes''' option, it's possible that Firefox is erasing your saved logins and cookies when you close it. Hope this helps.

Thanks, Wesley! I appreciate the thorough response. History settings were the issue.
