Afternoon everyone , 3 days ago I updated F/fox to V5 since then I have had problems with logging into the forum mostly it just fails but sometimes it will get to the forum page but when I try to sign in I get a message which is new to me as follows ''HTTP Error 400 The size of the request headers is too long '' is anyone else having the same problem?
At the moment I have gone back to using Chrome and there isn't any problem at all.
Will clearing the cookies help?
