Can anyone help with these error messages?
These are just the 'header' lines from the Error Console, Source code is pretty darn long.

I take no notice of who... I could have answered 1 or 20 of your questions today and have no idea.
So further info.
If you have issues clear the console, retry the action and take not of any errors that appear. That is about the only time it contains errors that are actually useful and offering diagnostic value in the problem solving process. The rest is fluff really.

Those error message (I think) are the result of opening an email from this support site. The guys that develop Mozilla support are not all that skilled in email they say. But it could be any add-on that that source. It is Thunderbird HTML sanitizer dropping unsafe commands. it may not in fact indicate any issue. My error console lights up like a Christmas tree with similar errors when I open RSS feeds.
So what is your real issue? You don't look in the error console without reason as a general rule.
I was checking the Error Console to see if could shine light on the 12/31/1969 issue, which you explained and solved in another post. Now I feel comfortable to 'clear' the error console
