Secunia Research Advisory - Multiple browsers suffer from multiple vulnerabilities. It is possible for a inactive tab to spawn dialog boxes e.g. the JavaScript Prompt box or the Download dialog box, even if the user is browsing/viewing a completely different web site in another tab. It is also possible for an inactive tab to always gain focus on a form field in the inactive tab, even if the user is browsing/viewing a completely different web site in another tab.
