Here is a sample URL that works on Microsoft Edge (current version) and receives an error message on Firefox (115.0.2): https://www.t-mobile.com/home-internet The error received from the web site when using FF is:

Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

FF was working with all T-Mobile pages a few months ago and now fails with this same error on most pages.

To test on Edge, I pasted the identical address that failed in FF into Edge and it worked fine so I am confident I am comparing the same web page on the two browsers.

Thanks for your help. Claude

Erasing T Mobile cookies fixed it. Some pages worked and some failed becaus T Mobile uses two domain names so you have to find the right cookies. This was not hard and onlyone cookie had to be deleted. Thank you for all the help. Claude
