HTTPS Everywhere for Chrome breaks redirects when authentication is required
I'm having a strange issue with HTTPS Everywhere. It breaks server redirects over HTTPS on my site when authentication is also required. It may also be related that I'm using a self-signed cert.
An example: https://nylen.tv/test should redirect to https://nylen.tv/test/ but it doesn't. The server is sending the Location header properly, but Chrome does not follow it and shows the 301 page instead. (The username for that URL is test and the password is testing).
What is even more strange is that if you refresh the page, the redirect happens like it's supposed to.
