All of a sudden I can no longer access a website that I have visited a million times before. I get an error message stating...

The page isn’t redirecting properly

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

   This problem can sometimes be caused by disabling or refusing to accept cookies.

I have cleared cookies/cache and all that achieves is that I can get to the website's log in page but then straight back to the same error message. I'm so frustrated as this is a website I need to access for my work.

I can get to it no problem on my phone so it appears to be a Firefox issue. I don't want to use another browser as I get on well with firefox but I fear I may have to as this is too important a website to be without.

Any help would be appreciated - thank you, Nat
