Qihoo 360 Browser – Fast and secure dual engine web browser

Qihoo 360 Browser


  • Secure Surfing & Download – Filter anti-phishing and malicious URL while browsing and scan downloaded file for malware.
  • Ad Filter – Hide unwanted advertisements to emphasize web contents.
  • Tab Search – Switch between numerous active tabs or open new desired tabs by entering keywords in address bar. Additionally, preface your keyword with @ to search among open tabs only.
  • Dual Engine – Powered by Webkit and IE web engines, 360 Browser optimizes the best webpage experience for you.

It uses chrome extensions.

Ad filter works good. Still needs improvement.

Biggest advantage using it is its malicious & phishing URL detection. It works really very good

Still needs some tweaking and performance improvement. How bookmarks are arranged and manged needs improvement. How tabs are handled when a large number of webpages are opened needs improvement.

I didn’t like the use of IE trident engine. It does not work well. So using only Webkit engine is recommended.
