- Chrome Web Store
- Mozilla Firefox Add-ons
These platforms have review systems and safety checks to mitigate risks.
2. Regularly Audit Your Extensions
Periodically check the extensions you have installed. Remove any that you no longer use or those that have not been updated in a long time. A single malicious extension can compromise your entire browsing experience.
3. Keep Browser And Extensions Updated
Ensure your browser and extensions are up to date. Updates often include security patches designed to mend vulnerabilities that could be exploited.
4. Use Antivirus Software
Having a reliable antivirus program can act as a safety net. Many antivirus software solutions can detect and prevent the installation of malicious extensions.
The Importance Of User Education
User education is perhaps the best defense against malware and harmful extensions. Awareness regarding what to look for and how to respond in questionable scenarios can significantly reduce the risks.
