Normally this error occurs on a website that is outdated in still supporting RC4.

RC4 support has been completely removed in Firefox 50 as it is no longer able to be overridden. https://www.fxsitecompat.com/en-CA/docs/2016/rc4-support-has-been-completely-removed/

This is the same site we discussed in your earlier thread: firefox said dont trust this website and l clicked ok, want to undo that?

If Firefox 50 no longer uses that workaround, you could switch to the Extended Support Release of Firefox 45. See: https://www.mozilla.org/firefox/organizations/
