Since last night every link I click opens in a new tab and it's infuriating. I tried copy pasting about:config into my address bar and editing the browser.link.newwindow things correctly but that didn't do anything. Does anyone have any other solutions? Also whenever I got to a certain site (deviantart) it highlights everything on the page if I click once, and sometimes when I'm typing it'll open a new tab or window or try to make a bookmark, which is really weird
