In swedish: "firefox har förhindrat den här sidan från att fråga om du vill installera programvara på datorn". Poor translation: "firefox has prevented this site from asking if you want to install a software on this computer"´. I do not get any say on the matter. Last draw was on add-ons, when trying to install adblock plus. I tried installing latest update. No luck. I've tried googling but only thing i found was to go to change change whether firefox should warn when websites try to redirect. That doesn't help. I don't want to decrease security, but I have to be aloud control. Problems seem to increase with every update.
