    when I’m trying to log in on memrise via Pale Moon I get an error message “Cannot POST /signin”.
    In the developer console I get an error about Content Security Policy, but I don’t think this is the exact cause.
    “Content Security Policy: The page’s settings blocked the loading of a resource at http (only 2 links allowed)
    app.memrise com/favicon.ico (“default-src ‘none’”).
    If I click the network tab in the developer console, I see the problem the website tells me.

The POST content is my e-mail and my password. The response is 404 (common HTTP error, file not found).

    Pale Moon 29.1.1 with a new profile (ensures default settings are used).
    Open memrise, enter credentials, then hit enter.

I had tome remove some dots because only 2 links are allowed for new users.
Kind regards
