visiting IMDB
It happened that visiting IMDB, a few times suddenly a huge red page appears with Firefox logo and a small window to download the file. I closed it the window right away and checked that my Firefox browser is up to date. It did not give the chance to take the print-screen page. So... what's going on? Does the site has a virus or what?

hi, this is a scam tactic that is trying to trick you into installing malware, so don't download or execute this kind of stuff just because of a popup or redirect on a website! updates are handled automatically by firefox so you don't have to download anything for that (and you can always initiate a manual check for updates in the firefox menu ≡ > help ? > about firefox).
we suspect this is coming form "malvertising" (=ads placed on legitimate websites that redirect you to this fraudulent message), so using an adblocking addon like https://addons.mozilla.org/firefox/addon/ublock-origin/ would also help with that.
