Windows 8.1, Firefox 99.0.2, eMail program part of Microsoft Office365 (deployed by university IT department) Login process worked fine for a month or so after implementation of a 2-level authentication (password plus a second method of user's choice - I chose a USB-flash device which [on request] sends a code for 2nd verification). All of the above still works, except that once logged in, the system asks me if it should remember me, or not (i.e., store a cookie or not, for future convenience). I always click "No". Now, when I do that, I get an error number 500, which is completely non-committal: "Something Went Wrong" - with a long garbage code. (See attachment for sample.) Results of tests to see what's wrong: 1) works fine (able to complete eMail login) under Microsoft Edge; 2) works fine on my laptop, running Windows 8.1 and Firefox 94; 3) on the 'problem' computer (desktop), I uninstalled Firefox 99 and downloaded/installed Firefox 93 - "500" error persisted. Just today: removed Firefox/Mozilla (including all folders/files, and Registry entries) then re-installed version 99. Still doesn't work. Let me know what else you need to know.

This is what I use; https://www.mozilla.org/en-US/thunderbird/ Thunderbird is a free email application that’s easy to set up and customize - and it’s loaded with great features!

Thanks, but I've already set up a 'workaround' - I downloaded Edge to use for the problem eMail program (only). What I wanted - and still want - is for Mozilla to fix whatever is causing the eMail program to fail in Firefox. (Remember that I said it does NOT fail on my laptop when everything is exactly the same, except that I use Firefox 96.x - that indicates to me that the problem is in Firefox.) I'll keep using Edge for this eMail program until someone figures it out.
