mozilla.org today released minor upgrades to three of its major products. Firefox 0.9.3, Thunderbird 0.7.3 and Mozilla 1.7.2 are all now available. These three new releases were created to correct 4 possible security vulnerabilities in past versions of each product.

I sugguest all who uses mozilla 1.7 or 1.7.1 to upgrade to the latest version that is 1.7.2 and netscape who going to release 7.2 in few weeks, they well have the fixes as well and well be based on 1.7.2 netscape users that still uses 7.1 can either wait for netscape new release or download mozilla 1.7.2
