content: A year ago, Firefox was the only thing remotely resembling a secure browser. <  3388  /p>  That's not really in line with the evidence though. Chrome is and has been better. For instance, at the second-to-last hacker competition in 2014, Firefox fared worst.  Also check the vulnerability count given in this post. Look at the vulnerabilities with a high security score. Firefox had a lot more than Chrome in 2015 (30 vs 8). Finally, having no sandbox is quite a security issue in itself.
