I found an error in "https://support.mozilla.org/en-US/kb/protect-your-thunderbird-passwords-master-password#thunderbird:win10:tb68" In the reset password section of "Tools>Developer Tools>Error Console" it says use <openDialog("chrome://pippki/content/resetpassword.xhtml")> which does not work. At the bottom it says the article is "Originally based on information from Master password (mozillaZine KB)" - http://kb.mozillazine.org/Master_password - but in that post the command given is <openDialog("chrome://pippki/content/resetpassword.xul")>, which worked. One problem I see in almost all Mozilla posts is there is no relatively easy way to report problems, no link to this page, and this page would discourage most people as it assumes one has a question to ask, not report an issue found. A link to this page should be on every article page sould a issue be found and the title of this page should be changed to something like, "Ask your question or report a found issue." I had to spend more than an hour to get this in place and only crazy, retired Information Security Analysts like me, or similar people, would likely bother to report problems, which is why some errors last a looong time like SHH's did.
