By the time that Mozilla gets done with the Beta phase of the development process there might be as many as a dozen Builds of the next iteration of the open source browser ahead of the first Release Candidate (RC).

Having suffered numerous delays, only 10 Beta Builds of Firefox 4.0 were slated for delivery initially.

With Firefox 4.0 Beta 10 already shipped, and with Beta 11 now cooking, Mozilla is revealing the possibility that Beta 12 could also be offered to early adopters for testing prior to RC1.

At this point in time, there’s no actual plan to build Firefox 4.0 Beta 12, with Mozilla still aiming to make Beta 11 the last testing milestone before the browser graduates to the Release Candidate phase. More »

Microsoft already confirmed one new feature for the Release Candidate of Internet Explorer 9, but apparently the company is also cooking some changes to the graphical user interface.

A recent video that made its way in the wild seems to indicate modifications to Tabbed browsing in IE9 RC.

Early adopters familiar with the beta development milestone of IE9 undoubtedly already know that the browser ships with a very simple UI.

This move is designed to put all the focus on the websites rather than on the browser, according to the IE team, and far from me to disagree with them.

IE9’s UI is certainly more subtle, and contributes to pushing the browser to the background and leaving site take center-stage. More »

Microsoft confirmed this issue, and noted that IE9 is not to blame, but that at fault is an incompatibility between the next generation IE browser and old hardware.

It appears that reports of poor performance for IE9 came from users that compared the speed of the new browser with that of older versions of Internet Explorer. The older releases of IE were faster especially on webpages that had complex graphics.

The issue is related to the HTML5 performance enhancements built into Microsoft’s next iteration of IE.

IE9 brings to the table hardware acceleration, leveraging the computer’s GPU (graphics processing unit) in concert with the DirectX APIs in Windows 7 and Windows Vista SP2. More »

Firefox 3.6.12 and Firefox 3.5.15 are now available for download to customers around the world, although the two releases were initially planned for availability in December 2010.

The fresh versions of Mozilla’s open source browser are part of the update process, although in this sense, their delivery is not in accordance with the browser vendor’s normal schedule.

Fact is that Firefox 3.6.12 and Firefox 3.5.15 are the equivalent of Microsoft out of band security updates.

While under normal conditions each new Firefox 3.6.x and Firefox 3.5.x release is a security and stability update, the latest refreshes are designed only to patch a vulnerability which older versions of the browser share. More »

An Internet Explorer 9 super Beta can be built by combining IE9 Platform Preview 6 released today October 28, 2010 at PDC and the IE9 public Beta made available on September 15th at the Beauty of the Web launch event in San Francisco.

At PDC 2010, Microsoft launched a new platform preview of Internet Explorer 9, the sixth developer release from the company.

Early adopters already familiar with the IE9 Platform Preview releases will find that the latest Build is intended for the same audience as its predecessors.

While IE9 Beta is designed as a wide testing milestone for the public, PP6 is intended for developers to test drive the latest platform enhancements that are built into the next generation of IE, such as CSS3 2D transforms and semantic tags.

Still, there is a way for developers to enjoy both the platform capabilities of IE9 PP6 but also get the site-centric user experience of IE9 Beta. More »
