NoScript Helps Reveal Website Exploits – Telegram .com Case
FireFox + NoScript
I usually suggest that you should use FireFox with the NoScript plugin for safer web browsing. This combo will save you from most web threats. Just remember one rule: Never use the “Allow this page” and the “Allow Scripts Globally” options.

Vulnerability Advisories for Third-Party Scripts
