If this MR had been merged it would have saved us a lot of time and trouble.

The amount of time wasted on this is ridiculous. Thanks. This is about the only thing that worked. Why in the world this wouldn't "just work" by defining the default url options in Rails config/environments/test.rb is beyond me.

It is also why it's implementation in firefox is completely useless, considering that windows/osx/most linux distros plan to add support for DoH/DoT/DNScrypt resolvers in the near future, so firefox doing it itself will provide no additional benefit.

Unfortunately, it's too late to make the question more specific as this would invalidate some of the (good) answers.

It will be useless work when gvfs-open will solve the bug, but in the meantime...

now that I realize how easy it is to just manually include this in my app: <%= javascript_include_tag 'xray', nonce: true if Rails.env.development? %> I regret even wasting my time getting it to automatically look for and add a nonce to the auto-injected xray.js script

Wasted too much time getting it to work with old Rubies/Rails, when I think the correct path should be to just remove support for them going forward
