Access Denied Error 21 message
I have a subscription to ancestry.com. However, I've noticed several Firefox updates ago that I can no longer write a story and add it to an ancestor's media gallery. When I do, I keep getting this:
Access Denied Error 21
What happened? This request was blocked by security rules.
Your IP: (gives my IP addy) Incident ID: (gives a different incident ID each time I try it and get the error message).
WHAT IS this? And how can I resolve it? I have completely deleted my browser history, cookies, cache, everything and it doesn't make a difference. I'm still getting this message but ONLY in Firefox. Not in other browsers. I use Firefox to do most of my genealogical research, but this may have to change if I can't get it to work with ancestry.com. I've also alerted them to the problem, but so far they haven't come up with a solution, other than to delete cookies/cache/history, which I have done. It can't be my computer or it would do it on all three browsers I have installed - Microsoft Edge, Google Chrome, and Mozilla Firefox. But it doesn't. Only in Firefox. It has to be something in the browser settings. Anyone have a clue?

According to an answer I found in Microsoft answers, you can try changing your DNS settings in Control Panel. The recommended settings are the Google ones, 8.8.8.8 and 8.8.4.4.
Your Firefox is probably set to use CloudFare (see Settings > General > Network Settings) so, before changing anything else, I would try making exceptions of ancestry.com and any related sites by adding them to the following preference in about:config. network.trr.builtin-excluded-domains
