confirmation code dialog not displayed
System: Linux pm01 5.4.0-42-generic #46~18.04.1-Ubuntu SMP Fri Jul 10 07:21:24 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux Firefox Version: 80.0.1
Within the last 2 days I have tried to access accounts that respond with something like enter the response code. Note-the firefox forum creation worked. The accounts were in Computershare.com and amazon.com. Both want to confirm (somehow) that the emailed code could be entered 'somewhere' on the screen, but nothing was shown that would accept an entry.
Just to confirm, I also tried Chrome and Opera and same thing. I even did it on my other Linux laptop with the same results. I don't do MS and even told Computershare that and they kept telling me to try a different browser to no avail.
