A. To minimize the risk of installing addons with backdoors, always check the permissions requested by the addon before installation. Go to the Chrome Web Store, find the addon, and review the permissions it asks for. If it requests access to data that seems unnecessary for its functionality (like access to all your browsing data), consider it a red flag. Additionally, look for addons that have a high number of downloads and positive reviews, as these are more likely to be trustworthy.
B. Regularly audit your installed addons. Go to Chrome settings by clicking on the three dots in the upper right corner, then 'More tools' > 'Extensions'. Review each addon and remove any that you no longer use or that seem suspicious. This helps reduce the risk of having potentially harmful addons installed.
