firefox enters incorrect password for yahoo email all of a sudden

Recently , after years of trouble free use I can't get into my email without correcting the incorrect password firefox tries to enter into YAHOO email . I tried using google AI to fix problem and all I got was a bunch of convoluted nonsense . This should be very simple . You save a login credential , firefox enters that credential for you next time you login . This sounds simple enough but what I got from AI was all this nonsense about cookies and tracking nonsense . I want things to be simple and direct . I NEVER SELECT REMEMBER HISTORY ...PERIOD . I NEVER SELECT "LEAVE YOU SIGNED IN" . The reasons are simple ...I WANT THINGS TO STAY SIMPLE .

The second I let firefox start leaving me signed in or remembering history , nothing but bullshit will follow . Now I have an issue which may result in me abandoning firefox entirely . Turns out the reason I got away from google is now what firefox is . Firefox used to be a straightforward browser that simply worked . Now its gotten complicated with all sorts of useless trash and here I am with a password manager that will not work for some completely convoluted reason . It enters a incorrect password . Any attempt to look in settings to correct problem is useless . The password I find is not even the same incorrect password it tries to enter !!!!!!!! This firefox is rapidly turning into shit !
