Firefox new tab has a box in the middle of the page for you to click in and enter text to search in your default search engine - and it immediately starts typing in the URL bar. IF I WANTED TO USE THE URL BAR I WOULD CLICK THERE.
Throws me off every time.
in about:config change browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar to false
So, changing that setting totally fixed the “issue” for me, for almost a week - but now the cursor is back to jumping up to the address bar from search, and that setting is still set to false. Any other settings you can think of to change?
