A new version of open source web browser Firefox has been released to fix a series of security bugs.

Firefox 1.5.0.4 fixes 12 vulnerabilities, five of them critical. The new release also includes stability improvements and fixes for memory difficulties. The update has also fixed a common bug affecting the clipboard for users of the Windows operating system.

Security announcements from the Mozilla Foundation, which produces Firefox, warned that the critical bugs could also affect its Thunderbird e-mail client.

“Thunderbird shares the browser engine with Firefox and could be vulnerable if JavaScript were to be enabled in mail. This is not the default setting and we strongly discourage users from running JavaScript in mail.”

The update marks the third month running in which Firefox has released new versions to tackle security vulnerabilities. The open source browser is increasingly popular and now has 10% of the browser market share.
