My t-online-Password + my e-mail-adress are not accepted in Firefox. An other Browser just accepts them, cause they are valid, The same with my Avira-Password, it is claimed to be "wrong". On my new notebook Firefox now has become to unhandy for me and no: mostly I fill in the Password and my user name correctly and I am tired of trying again and again if I made a mistake while another Browser just accepts the correct Password, which always did work also in my firefox on my Desktop - because I do not fill them every time newly (and maybe wrong), they are saved and are being autofilled. It's a pity I cannt continue to work with firefox and have to switch to another Browser (or several others), because it is no fun to try for hours to find the cause for pass words that Firefox does not accept.

If your passwords go through a cross site check they will not work until you adjust the Privacy and security settings:

UPDATE: Follow the above guide:

Get to Customise Tracking Protection > Advanced settings > Customised tracking protection > Cookies >

I block All and add each site as needed, so if you cannot find the site then you will have to Allow all cookies
