I'm a developer of a web portal for a german energy supplier based on HCL Domino. The login which uses AJAX/XHR and Dojo worked for the last 8 years and until Firefox 142. But with FF 143 it's impossible to login to the user acount. I can't recognize any error in the dev tools, The request returns status 200.

Has anything changed from 142 to 143 concerning this handling?

Thanks in advance :-)
