I\'m using Firefox, and while setting up a server, I have been fiddling around with redirects. Now, Firefox has cached a 301 redirect from http://example.com/ to https://exa
I tried the 'correct' answer, plus the comment about including cache in the deletion, and I was still having issues with my problem site.
I opened the firefox profile directory and searched for the website name in all files.
I found it in 'logins-backup.json' and deleted that file to finally fix the problem.
