@Vlad I was not aware this was an option. I just tested it and the bug is present with automatic https upgrade
both on and off.
if I don't explicitly specify the protocol like: http://ryanair.com
and instead just type ryanair.com
then it Orion automatically pre-fills it with https: here's video demonstrating how the toggle isn't making any difference.
I personally think that it's important and good that Orion prefers to use https over http as the default protocol. but for proper site compatibility and truly make Orion the default browser for many it needs to be reliable and have maximum compatibility.
Solution suggestion
for automatic https upgrade
= off
Orion should be "smart": where Orion attempts to load the page using https by default (so far no changes): if the page doesn't load then Orion should attempt to load the same page with http before failing. This way we get maximum compatibility while maintaining security.
