Describe the bug

I just got a notification that the old Github integration is deprecated and I should update. Adding the new Github integration results in the following error message, which prevents any configuration:

To Reproduce Steps to reproduce the behavior:

1. Go to a room

Desktop (please complete the following information):

• OS: ArchLinux

Hiya, having looked into this, it appears to be the Firefox privacy settings causing this one:

If you set the privacy setting to anything more lax than "Cookies from unvisited web sites" then this should work, but Firefox seems to be blocking cookies from websites you haven't directly visited. The integration manager works by loading in an iframe of the bridge's configuration widget, so it's entirely possible that it's paranoid about that.

The Strict setting should also work. In the meantime, we will look into how to make it less paranoid.

These are my settings, and they're staying that way. I hope you can find a way to make the integration work with these settings.

Right, solution coming up in https://github.com/matrix-org/matrix-hookshot/pull/678. The use of local storage in this case is an optimisation, but we can work around it.

Workaround was deployed.
