Firefox redirects to https

Question

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

Answer 1

"Sites preferences" are the culprit. Wasted 45min of my life finding how to fix it despite all the kb/support.mozilla tricks which does not solve your issue nor did mine. I dunno what triggers this issue but several of my websites started to go pear-shaped in a few weeks only affecting me and only firefox.

That's the solution you are all looking for:

1. Go to Preferences
2. Privacy
3. Click 'Clear your history' (nothing will happen yet, click safely)
4. Once the pop-up appears, click Details.
5. Untick everything except 'Sites Preferences'
6. Select 'Everything' in the select box at the top
7. Click Ok
8. Try now

PS: What I did try that did not worked for me are:

• urlbar.autofill false
• Forget Website trick
• Safe mode
• We all know it is not an HSTS issue when a website you own and you accessed before never got https support but now FF wants you to use https... It is just a firefox bug IMO.
