Two of the most well-known alternative browsers received security updates recently. On Thursday, Opera released version 9.51, focusing mainly on stability and security issues. The latest version of the browser resolves problems with search engines when upgrading from Opera 9.2x and a stability issue when printing. It also fixes a previously undisclosed arbitrary code execution vulnerability and delivers various performance tweaks detailed in Opera's release notes.

The release of Opera 9.51 follows an update to Firefox issued earlier this week that resolves a dozen bugs found in version 2 of the open source browser, including a few remote-execution vulnerabilities. Users are advised to upgrade to version 2.0.0.15, or better yet move to Firefox 3.0, which is not affected by these particular bugs and offers improved performance, stability, and memory usage.
