The next version of the Firefox web browser, Firefox 1.5, is slated for release later this summer, and development work continues on features that include an automatic update service.
Developers are making good progress in adding features to the upcoming Firefox iteration, including development tools that can be used to encourage additional web applications for the browser.
First and second alpha releases of the new browser were released last month. A beta version is expected soon, but no specific date has been offered.
Earlier this week, The Mozilla Foundation announced that international versions of Firefox and the Thunderbird e-mail client would be delayed so that recent security fixes could be included. The delay arose from a number of software glitches that were introduced in last week's release of English-language versions of Firefox and Thunderbird.
The open-source browser was released in November and has grown as a popular alternative to Microsoft's Internet Explorer browser and other competing products.
By April, Firefox had been downloaded 50 million times, according to the Mozilla Foundation.
