Mozilla Error Message - no support needed!

Making moves

I realize that Mozilla Support is the place for help with technical or performance issues, however I don't really need help for this issue, but I believe it still may be of interest to Mozilla.  Today, as I reviewed my AMEX credit card activity, I clicked into a Apple.Com/Bill entry for more detail, by clicking "receipt" which always brings up the specific detail transaction.  But this time I received this message: "HTTP Error 431 Request Header Fields Too Large".  So, after trying a few more times, on other Apple.Com/Bill transactions, and getting the same message, I logged off of all programs and restarted my computer.  Upon restart, I logged back into Mozilla, and then into AMEX, but again received the same error message.  I then brought up the Google Chrome browser and logged into AMEX.  This time, when I clicked into "receipt" on one of the AMEX charges, it quickly brought up the detail that I was expecting.  So again, I don't need any help, but I thought someone with Mozilla might be interested.   Bud Carlson
