Few changes made to Web browser in update of open source suite The Mozilla Foundation updated its Mozilla open source Internet suite and added services to its Web site Wednesday, including an option to obtain telephone support.The Web browser, the central component of the software suite, changed little, but new features in other elements include a spelling checker in the e-mail client, and additions to Mozilla Composer, a Web page editor, allowing images and tables to be more easily resized and repositioned. Chatzilla, an IRC (Internet Relay Chat) module for Mozilla, has also been substantially revised, the foundation said in a statement.Behind the scenes, Version 1.5 of Mozilla fixes a number of bugs — but also introduces new problems, including one that prevents some Linux operating system users from viewing Web content using RealNetworks Inc.’s Realplayer plug-in and the new browser. The problem arises because different versions of the GCC compiler are used to compile the browser and the plug-in, according to the foundation, which is based in Mountain View, California. The new software is available for machines running Linux, Microsoft Windows, or Mac OS X. It can be downloaded from the foundation’s Web site at http://www.mozilla.org, or bought on CD. The CD contains versions for all three operating systems, and costs $3.95 plus shipping and handling, the foundation said.The group is also offering end-user telephone support for $39.95 per incident. DecisionOne Corp. of Frazer, Pennsylvania, which provides technical support to several enterprises and software vendors, provides the support service. Software DevelopmentTechnology Industry
