I don't know if this is an issue on my end or not, but when I navigate to Kitsu in Chrome (currently v58.0.3029.110, but issue was first noticed around v55), I get a blank white screen.
I am currently accessing Kitsu via Firefox, which works fine, and I was able to access Kitsu via Chrome on another computer, though I suspect it has a much older version of Chrome. My computer is running Windows 7 x64 (the other computer I tested is running the same OS).
When I bring up the Developer Tools by pressing F12, I can see the following messages/errors:
Message @ kitsu.io/:38: Resource interpreted as Stylesheet but transferred with MIME type text/html: "https://kitsu.io/assets/client-fe1a8037dff2132a4a602cbc5e79ca0f.css".
Error @ kitsu.io/:1: Refused to execute script from 'https://kitsu.io/assets/app-19629bb000735e04596144c34038e155.js' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.
Error @ sw.is:1: The script has an unsupported MIME type ('text/html').
Error @ sw.is: Failed to load resource: net::ERR_INSECURE_RESPONSE
When I googled the issue, the only people I could find talking about it were webapp developers, and their suggestions for fixing it were all app-side, which I cannot really accomplish.
I've attached a screenshot for clarity.
EDIT: I should clarify that I also tried disabling all of my extensions, and got the same results. However, I can navigate to Kitsu without problem in Chrome's Incognito mode.
