search.hfreeforms.co This "website" has inserted itself onto my computer and opening a new firefox tab takes me to it. How do I delete/remove this succubus?
Whenever I enter "New Tab" the string above appears in the address line box, and I am in Yahoo; before this started a few hours ago, I would get a new Firefox tab with my saved sites appearing. I recall entering a new site trying to view a basketball game, and this started just after. I restored my computer to a point a week ago, but did not fix. I blocked all permissions for the offending website, but want to know how to delete it.

First, let's make sure your system is clean.
You may have ad/mal-ware. Further information can be found in this article; https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-caused-malware?cache=no
Run most or all of the listed malware scanners. Each works differently. If one program misses something, another may pick it up.
You said this is with the newtabs page?
With Firefox 41 (and higher), it's no longer possible to customize the page shown in a new tab via changing the preference browser.newtab.url in about:config. Because of the fact that hijackers abused the preference in the past, Mozilla decided to remove it (see bug 1118285). Fortunately, by removing it, Mozilla also introduced a new API to bring this functionality back to life as an add-on. This add-on allows the user to choose a certain page in a new tab.
