Thunderbird, now discontinued, also gets security and bug updates
Mozilla today made available version 17 of its Firefox desktop browser, bringing a number of functionality fixes and security upgrades. The upgrade brings an improved Awesome Bar experience with larger icons, revision of the Social API and support for Facebook Messenger, and click-to-play blocklisting to prevent vulnerable plugin versions from running without user permission. The version update brings one major exclusion, though: it drops support for Mac OS X 10.5 Leopard.
Program shifting to curated security releases only
Mozilla's Thunderbird email client has reached the end of active development, according to a blog post from Mozilla Foundation Chair Mitchell Baker earlier this week. Thunderbird is going to be split into two releases: Thunderbird ESR, which will be released in final form in November; and vanilla Thunderbird, which the Mozilla Foundation intends to be advanced by users of the product.
New multi-platform mail client posted by Mozilla
Mozilla has put the final release of Thunderbird 5.0, its email client software, up on its servers for downloading. 5.0 represents the app's first major release in about 18 months. The free app (Windows, Mac OS X, Linux) has faster startup, tabs that can be reordered and dragged to different windows, attachment sizes are displayed along with the corresponding attachments, and support for Mac 32/64 bit Universal builds. The latter means that, unlike earlier releases, Thunderbird 5.0 will not run on PowerPC-based Macs.
Drops support of PowerPC Macs
Mozilla has released the first beta of Thunderbird 5.0, its forthcoming multi-platform email client. The beta makes a raft of changes, including the introduction of a new Addons Manager and extension management API. Plugins can now be loaded in RSS feeds by default, and an altered account creation wizard should provide better setup.
Mozilla, Apple fix exploit
Crash errors in Mozilla's Firefox browser have been fixed with help from Apple, the organization says. Bugs in earlier versions of Firefox 3 were said to have been crashing the software, sometimes generating memory corruption at the same time; Mozilla comments that while no threats have emerged, the potential existed for launching arbitrary code, such as malware. Two of these bugs -- found in the image rendering code -- were discovered by Drew Yao of Apple Product Security.
Firefox 2 and 3 updates
In an unusual move, Mozilla has released updates to two versions of its Firefox web browser. The current browser has been updated to v3.0.1, while its otherwise outdated predecessor has been updated to 220.127.116.11. One of the reasons for the patching is a remedy to a potential "carpet bomb" attack against Windows users, who must have both Safari and Firefox installed on the same computer. The attack also requires that a person actually have Firefox closed, while still running another online application. Having even the unpatched browser up and active will prevent any intrusions.
