Recently, I've been using Firefox to get onto the site Fanfiction.net. But recently I've been getting an error message

(Error code: sec_error_ocsp_invalid_signing_cert)

I've tried the solutions people with the same or similar problems have and nothing has worked. Fanfiction.net works fine on IE 11, but it messes up on FireFox 31. What can i do to fix this so that i can get back onto this website?

That could be a problem with the usage of libPKIX in the Firefox 31 and later releases.

It is possible to disable this new feature by disabling libPKIX support, but this is not recommended for security and vulnerability reasons.

  • about:config page: security.use_mozillapkix_verification = false

It is possible that the website will fix this issue shortly, so make sure to check regularly if this workaround is still required by resetting the pref and see if it works. You may have to reload and bypass the cache via Ctrl+F5.
