This comment was split from the discussion: .asp pages not loading or not visible

I continue to have a problem with one particular on-line vendor's eshop: As it turns out, this shop does not use .asp pages. Nevertheless, I cannot view it. The link to it on the vendor's home page ( does not work for me. Links to it (or individual items) do not work; all I get is a blank page. Pasting a link to any item in his inventory into a new browser window does not work; it only generates a blank page. Links to items in emails do not work; again, all I get is a blank page.

This problem began when I updated to FPR 17. I use a script blocker (NoScript 5.1.9) and uBlock Origin v1.11.0, but the site in question is whitelisted for both.

The owner of the site assures me that I am not blocked at his end.

    I split this post from the original discussion since it is not related to .asp pages.

    While the homepage loads fine, links to items like this one (which I am very tempted to buy) do not work:

    This looks like a security problem (Cameron – missing cipher for TLS 1.2?)

    As a temporary measure you can do the following:

    • type about:config in the URL bar, hit enter
    • confirm you'll be careful
    • search for network.http.spdy.enforce-tls-profile
    • set this to false

    That fixed it! Many thanks. But will that cause problems with other sites? When I see "security problem" I get a bit anxious.

    P.S. You'll enjoy building the HAL 9000 interface.

    As far as I understand, this setting does make the browser a tiny bit less secure, but it won't cause problems with other sites.

    Uplifted to issue 576, since it is probably either the same issue or related:

    This is actually a regression from a hack I installed to fix Amtrak. I'm looking at workarounds but getting both working at the same time probably means a major crypto upgrade. For the time being, a better fix is to set security.ssl3.ecdhe_rsa_aes_128_sha256 to false (and then set network.http.spdy.enforce-tls-profile back to true).

    This is fixed in FPR19 beta.
