Start Firefox in Safe Mode {web link} A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

No, the issue is not there when I do this.

Thanks for your help. After I removed the extension DuckDuckGo essential that I installed long time ago was causing the problem. I removed it and everything works fine.

I think you did not understand what was my issue. The issue is that the sites having only http in url are redirected to https and show the security risk warning. Sites having https in url are loading properly.
