The dashboard when you click on the icon to open it. Not called a dashboard? What is it?
I fixed that.
BUT yesterday, again, it was not opening. This morning, yes.
Re copying the custom filter list.
I remember getting those instructions.
My page doesn't look like you described, though. I see no check box on the top left corner of the filter table. Unapproachable triangle on right side, though.https://imgur.com/a/iqWOsxe
You are right. It seems like a persistent and broad range of problems.
I just updated FF to 85.0.2 yesterday.
Still getting multitude of annoyances - mostly script errors and *A webpage is slowing down your browser.*
One of the repeated script errors in Outlook.com is this:
“A script from the extension “Adblock Plus - free ad blocker” is running on this page, and making Firefox unresponsive.
It may be busy, or it may have stopped responding permanently. You can stop the script now, or you can continue to see if it will complete.
