hello WNxBrontus, this sounds like a problem possibly caused by adware on your pc. please go to firefox > addons > extensions & remove any suspicious entries (toolbars, things that you have not installed intentionally, don't know what purpose they serve, etc). also go to the windows control panel / programs and remove all potentially unwanted software. [[Remove a toolbar that has taken over your Firefox search or home page]] afterwards you can either install the [https://addons.mozilla.org/firefox/addon/searchreset/ searchreset addon] to get rid of the problem or manually reset the page that opens on each new tab - enter '''about:config''' into the firefox location bar (confirm the info message in case it shows up), search for the preference named '''browser.newtab.url''' and right-click & reset it to its default value (about:newtab).

thanks for the help, it was really getting to me
