Frequently Asked Questions (FAQ)

Do you need security extensions for your browser?

A security extension adds a layer of protection inside your browser, where many threats start. Keeping your browser updated is essential, because browser makers regularly release emergency fixes for actively exploited flaws, but updates only fix problems that are already known.

Security extensions can warn you about phishing and malicious sites, block dangerous downloads and trackers, and flag risky links before you click. Install them only from official extension stores, check the permissions they request, and use them alongside antivirus software rather than instead of it.

What risks do I face without browser protection?

Without protection, a single malicious link, download, or fake login page can compromise your device or accounts. Common risks include:

Identity theft and stolen passwords from phishing sites
Financial loss from banking fraud or ransomware
Malware that steals files, emails, or photos
Browser hijackers and adware that slow down your computer
Loss of important business data

Safe browsing habits combined with up-to-date security software greatly reduce these risks.

How is a browser security extension different from antivirus software?

A browser security extension works inside your browser and focuses on web threats: it can block known malicious sites, phishing pages, and harmful downloads before they reach your device. Traditional antivirus software protects the whole computer and scans files, apps, and system activity for malware from any source, including email attachments and USB drives. The two complement each other, so most people benefit from using both rather than choosing one.

Will Browser Security Extensions slow down my computer?

Usually not noticeably. Well-built security extensions are lightweight and use few system resources on modern computers. However, every extension adds some load, so running many at once can slow your browser, especially on older machines. Install only the extensions you need, keep them updated, and remove any you no longer use. If your browser feels sluggish, its built-in task manager or extension settings can show which add-on uses the most memory.
