%TMP% did nothing to fix the issue.
I do not have DuckDuckgoLite.
Removed and replaced Duckduckgo as an added search engine but did not fix the issue.
Tomorrow, I will set up a new Firefox profile and see if I can replicate the issue.

None of your suggestions have changed anything and today I have found additional problems that are really irritating. If I go down the search results list to any website, open the web site, exit the website then back at the search results page, I can mouse scroll down but if I hit the down arrow, I am taken back to the search results beginning and must start all over scrolling down the list. I think that I will totally uninstall duck and reinstall and see if that works.
