The recent update of Mozilla’s Firefox web browser from version 3.0.10 to 3.0.11 fixes close to a dozen security flaws of which 4 were rated as critical.
So don’t delay updating but rather play it safe.
You can find additional details at the Mozilla website.
As The H Security reports, Mozilla’s SeaMonkey and the Thunderbird mail client are also subject to the vulnerabilities. Updated versions SeaMonkey 1.1.17 and Thunderbird 2.0.0.22 resolving those issues are expected soon.
