'Critical Firefox Update' Pop-Ups

Various users have reported the presence of the 'Critical Firefox Update' pop-ups while they are browsing the Web.

These alerts are not to be trusted, as they do not serve to provide you with a Firefox update like they claim. Instead, the 'Critical Firefox Update' alerts will ask users to download a '.JS' file. The file in question is called 'firefox-patch,' and it may seem harmless at first glance. However, if you run the 'firefox-patch' file, you may notice some changes in your Web browser. This is because the 'firefox-patch.js' file will tamper with your Web browser's settings automatically. Needless to say, this is a red flag as genuine tools and services would never alter your system's settings without your knowledge. Once this shady file is present on your system, it will make sure you are bombarded with advertisements as soon as you browse the Web. The activity of this pest is rather similar to that of adware. However, it may be rather difficult to rid yourself of the advertisements affiliated with the activity of the 'Critical Firefox Update' pop-ups. Fortunately, a genuine anti-virus application can revert the changes linked to the activity of the 'Critical Firefox Update' pop-ups easily.

Websites that attempt to push shady software, masking it as important updates, are never to be trusted. If you want to update your software, make sure you do so via the pages of the official vendors of the product.
