The Mozilla Foundation has postponed releasing the next major version of its open source Firefox browser to September as it gets to grips with bugs in current versions.
Firefox 1.1 had been promised for this month, but Mozilla has just released two browser upgrades in the space of a week to counter security vulnerabilities and bugs.
The current version of the browser is 1.0.6. Mozilla has now decided to scrap 1.1 and create version 1.5 in September. Mozilla says versions 2.0 and 3.0 will appear at some point next year, as it continues to introduce new features.
The biggest change brought by version 1.5 will be a new incremental updating system to handle security fixes and other updates.
Currently, Firefox users have to install a completely new browser every time Mozilla issues an update to Firefox. As well as taking longer to download a fully updated browser, the current system could be acting as a deterrent for some users to fully patch their system.
Mozilla will instead introduce a browser update system similar to the one used by bigger rival Internet Explorer and other browsers, which allows users to download only a patch when it appears.
