Mozilla on Wednesday released an update for Firefox 1.5 that fixes several security flaws and makes other changes aimed at improving the open-source Web browser.

The update, Firefox version, patches a total of eight security vulnerabilities. One is deemed "critical" by Mozilla, four are rated "moderate" risk, and three are tagged "low" risk. The more serious flaws could let an attacker take over a system running a vulnerable version of Firefox, according to Mozilla's security alerts.

Among the issues tackled is a problem disclosed late last year, which concerns Web pages with an extremely long title that could cause Firefox to crash.

Security monitoring company Secunia rates the Firefox update "highly critical." Mozilla recommends that all users switch over to this latest version, according to the Firefox update release notes.

Aside from the security fixes, the update delivers improved stability and support for the Mac OS X platform, according to the release notes. Users of Firefox 1.5, first released last November, can upgrade to the new version using the automatic update feature, or it can be manually downloaded from a Mozilla site.
