Error Message
I have been signing in to a certain secure website for years on Firefox. In the last 24 hours, it won't let me sign in and all I see is:
"Bad Request
Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit."
I have tried 20 times. There is nothing wrong on the website; my wife can access the same on her Mac computer.
Any advice? Thank you
