Going online is fraught with all manner of dangers. There are viruses top be concerned about, malicious websites, phishing attacks, hackers and so much more. We have – for the most part – become used to the idea of having antivirus, antimalware and firewall software installed, but our web browsers can also play an important role. This not only means making sure that you choose a reliable browser and keeping it up to date, but also investigating the extensions that can be used to further bolster security.

If you are a Firefox user, security firm Kaspersky has a browser extension that can really help you do just this. Kaspersky Protection 2021 takes a multi-pronged approach to protecting not only your security, but also your privacy when you're online.

The extension blocks the tracking components that are found on many websites, helping you to stay slightly more anonymous online. On top of this, it can also block banner ads to make your online experience rather more enjoyable. But it is in the field of security that the extension can really help you out.

Kaspersky Protection 2021 can automatically check the validity of the sites you are visiting. This is a great way to ensure that you don’t fall victim to malicious sites masquerading as your bank or some other institution. It can also advise you about the security level of individual sites, helping you to make informed decisions about the types of information you might be willing to share with them.

In addition to providing you with information to help you to make educated decisions, the extension can automatically block any content that is deemed dangerous by Kaspersky. There are some other neat elements to Kaspersky Protection 2021 such as an on-screen keyboard for interception-free data entry of private or sensitive data, and also a special, ultra-secure Protected Browser mode for when you are visiting finance -related sites.

Perhaps unsurprisingly, the extension has been designed to work in conjunction with Kaspersky's desktop security software, but it is still possible to use it on its own.
