Hi Jeff, this domain doesn't sound familiar, but it does seem to be associated with ads or adware in search results.

I think there are two primary possibilities. Either:

(1) A web page you are visiting is making a request to that site (either the site itself or something embedded in the page), or

(2) One of your add-ons is making a request to that site

Do you notice any patterns related to when this happens?

Please, provide info about addons from about:support https://pastebin.mozilla.org/

Also, try to clear a cache. Use for that a popular special software where you can see a cache for each website. Try to find something like this url or ip. And destroy that.

Oh, thanks. I forget sometimes.

Jeff, your addon's list is strange enough. It may contains included ads. So, turn off all and try without. If ok, let's start some addon and check with it and repeat for each addon.

Finally, you may try a Safe Mode.
