Hello FrankStock, That 'Omnibox' is a browser hijacker, malware that you will of course want to get rid of. Would you please go the 3-bar menu => Add-ons => Extensions and remove anything you might see there that you didn't install yourself. Do the same in Windows Control Panel => All Programs. Then, would you please run '''every''' malware scan that is listed in this article : (what one doesn't pick up, the other one will) https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-caused-malware Also see : https://malwaretips.com/blogs/remove-omniboxes-virus/ ------------------------------------------------------------------------------------------ Separate issue : Your system details show that you need to update your Adobe Flash Player - you're running an older version, which can cause problems.
