ADENDUM: I think the inability to format the question can be viewed by some as a reflection of quality in FF. The list I included in my post was one per line, The + sign is attached to most recent link to it's left. I reproduced it here, where formatting IS allowed. Wow!

It is a long standing bug that you do not see the first question post formatted (there is an extra DIV in the DOM), only subsequent replies appear formatted.

You would have to contact the developer of the extension if you aren't satisfied with the way it presents its information.

Data that you really need for proper functioning can be retrieved from various CDN and other servers, so if a website isn't working properly then you would have to disable the extension for this website (i.e. allow all content) if you aren't able to determine what domains to allow.

The gravatar website is for the avatars, see also the Web Console and Network Monitor.

A big thanks to you cor-el for your input. You said "You would have to contact the developer of the extension if you aren't satisfied with the way it presents its information."

1. That's why I posted this!!! - I CAN'T, am UNABLE, and don't understand why one has to create a email account with Moz in order to talk to them. Catch 22.

Thanks for the suggestion but ummm... duh!

I have been through the github and the 'page' for the add-on. To ask the question at the add-on page requires one to have a Mozilla email account. Why the need for having to get another email account to pose one question?

Gorhill uses Github & AMO (addons.mozilla.org) to distribute his uBO add-on. You will have to file an issue over at his Github uBO page (https://github.com/gorhill/uBlock/issues)

GitHub and AMO have their own DBs, you need a separate account for both. If you are trying to use your SUMO account log in details from here, that won't work. All *.mozilla.org/com domains need their own email/password. The AMO site is only for adding reviews about the add-on and is not to be used for getting tech support. You'd go to GitHub for that.

If you can't get through via Github, his support site links to a Discourse community which needs a separate login. https://discourse.mozilla-community.org/t/support-ublock-origin/6746

I marked this as solved, though it's not. Thanks any way. I'll just uninstall it and find another. When one add-on wants a new Mozilla email account, and according to your note, are not even associated with Moz, except for the add-on, there are also others that don't. Things sure got clunky since Netscape - progress?

Thanks again and to all volunteers @ Moz.
