Whoa, that's very broken. Over the years, Firefox went from checking DNS first for a "one word" query, then searching if there was no matching host name found, to searching first, but checking for a matching host name in the background. Normally, a one-word query would only match an intranet server, and so that feature can build a small list of exceptions. But, it seems you have a dishonest DNS resolver that says there is an ebay (not ebay''.''com, just ebay) server. Sometimes this a "feature" of your ISP and other times it may be caused by an add-on or external software. It nearly always features a page of pay-per-click links by someone who hopes to profit from the lie. So first, lets clear that ebay entry from your preferences: (1) In a new tab, type or paste '''about:config''' in the address bar and press Enter/Return. Click the button promising to be careful or accepting the risk. (2) In the search box above the list, type or paste '''fixup''' and pause while the list is filtered (3) Find the '''browser.fixup.domainwhitelist.ebay''' preference and right-click > Reset it so that Firefox removes it (this doesn't happen instantly; you can reload the page in about 30 seconds) Next, let's see whether you can learn who the liar is: (4) Double-click the '''browser.fixup.dns_first_for_single_words''' preference to switch the value from false to true Then, in another tab, toss ebay into the address bar and submit that and see what kind of response page you get. Often there is an explanatory or opt-out or uninstall link near the upper right or at the bottom. Can you learn anything more from this page? (5) To restore searching precedence over DNS, double-click the '''browser.fixup.dns_first_for_single_words''' preference to switch the value from true back to false
