Hi   !
These are fake updates   !
Please, don't ever click on anything on these pages   ! Firefox will always update from within the browser and not from a random webpage. Scammers have been using this tactic, trying to get users to download and infect their computer. Hard to get rid off, as they will change their URL on a daily basis.

You could consider an ad-blocking add-on like :

thanks. i had no idea these ads were not from firefox itself. i installed the addon popup filter so we shall see what happens. these popups have been annoying me for months!

Hi, note that XP is supported up to v52 and you are running v47 so some notifications may be genuine - Firefox has ended support for Windows XP and Vista

You can check for genuine updates yourself, by opening the 3-bar menu > Help (question mark at bottom right) > About Firefox. Alternatively, you can press the Alt key to bring up the main menu bar > Help > About Firefox. More - Update Firefox to the latest release.

Yeay, these fake updates are a real pain in the toosh. Hopefully you will have seen the last of them   (fingers crossed). But should you see them again : You know what to do   -   or rather :   what   not   to do   !
