When did you last check the browser extensions installed on your computer?
Microsoft recently removed 119 malicious extensions from the Edge Add-ons store after discovering they had been downloaded around 2.6 million times. These included everyday tools like ad blockers, PDF editors, VPNs, translators and video downloaders.
What made these dangerous was the delay. Many waited days before doing anything harmful, making them much harder to spot. Once active, some were stealing browser data, redirecting users to malicious sites or installing additional software.
Most browser extensions are perfectly safe and genuinely useful. But they deserve the same attention as any other software you install.
If you no longer use an extension, remove it. If you do not recognise one, find out what it does. If one is asking for more permissions than it needs, question why.
Attackers know that familiar and convenient tools rarely get questioned. That is exactly what they count on.
How many browser extensions do you think are installed on your devices right now?
