Family members updated Firefox to 68.0.2 After doing so, they could log in to AOL but when trying to access their mail, they'd get an error about an improper redirect. Standard procedure was tried. Cleared Cache, Cleared Cookies, Forgot Site Booted Safe Mode Refreshed Firefox Deleted .sqlite files for cookies Wasn't able to find any button for disabling Content Blocker in this version of Firefox but since everything was default, I doubted that was the issue. It was only blocking trackers. I even tried to solve the issue by following the instructions to disable DNS prefetching in the help article: https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can And while I'm here, please Mozilla... Bring back the option to completely disable checking for updates to the masses. I am the administrator/manager of the tech in this household, I don't need popups/notifications/prompts showing up for the other users of this rig to update things while I'm away.
