Cannot sign into Google/Gmail on updated Firefox 76

Running a 2019 Macbook Pro on Catalina 10.15.4. I take decent care of it in terms of closing applications not in use frequently, charging when battery hits 15%, and restarting it at least once a week. I had to change my default browser to Chrome throughout the schoolyear since Duo dual authentication did not work properly with Firefox. Now that I have graduated, I wanted to jump back to Firefox and updated to 76.0.1. Unfortunately, I cannot sign into any Google accounts.

I am presented with an option to select a Google account, or select add/remove additional GMail accounts, but all UI features are nonresponsive. The "next" button does nothing, selecting add or remove accounts does nothing. I have since restarted my computer, cleared all data and cache from Firefox, uninstalled and reinstalled firefox, and cannot seem to figure out what is the problem here.

Same thing here but on Windows 10. At first I was experiencing UI problem in gmail, then realized that I could not access and connect to any other of the google apps, or to accounts.google.com. So I cleared the cookies and site data, logout, and I know I can't log back in. Rebooting the PC didn't change anything. However, everything works fine with Edge browser, and on iOS.

I'm using Windows 10 on my PC, too. Google Mail doesn't work after upgrading to Firefox 76 but it works on my Android phone and on Google Chrome on my PC.

I tried going in to Firefox safe mode but that didn't make any difference.
