Whenever I open Firefox I'm asked to download impression.link. It's keeps popping up even though I cancel. I've tried saving it to make it go away but each new tab I open in Firefox browser I get the same all over again. Impression.link pops up and asks whether I want to save or run it. I've never had this before and it's extremely annoying as I don't know if it's a threat. Do you know what this is and how do I stop it.
