🧩 Browser extensions can boost productivity, block ads, manage passwords, and more — but not all of them are safe.
Many extensions request excessive permissions like “read and change all your data on the websites you visit.” Some are even designed to spy on you, inject malware, or redirect search results for profit.
Once installed, a malicious extension can act like spyware — and you might never notice until it’s too late.
⚠️ What Can Go Wrong:
Stolen login credentials
Browser hijacking (e.g., fake search engines)
Targeted phishing or advertising
Background crypto mining
Data exfiltration from forms and cookies
🛡️ How to Stay Safe:
Only install extensions from trusted developers
Check permissions before enabling
Avoid extensions with low installs or vague descriptions
Regularly audit and remove unused extensions
Use a secure browser profile with privacy settings enabled
💡 Quick Tip:
🔍 If an extension needs access to everything — it might take everything.
