duplicate of /questions/1466153 thread

I thought I had solved this by adding the website to the "safe" list - I really cannot say how frustrating this is if I am being locked out of even safe sites. - This is a browser issue (I'm not that naive).

There is no real response from Moacilla(Firefox) here apart from throwing the Rulebbok at me and saying "Read!". I can only do so much Tune ups" and shut downs and ensure drives are functional. Please advise on the Browser Cache situation, rspecially as BBC iPlayer is added to the "Safe List" and yet still throws up the 400 Bad Gateway error message - an early reply would be useful.

Example of sites causing this so others can test if they get the same problem or not?
