Mozilla launches final Firefox 3.0 beta

Firefox 3.0 Beta 5 has landed on Mozilla's download servers

Mozilla unveiled the final beta of Firefox 3.0 Wednesday and will move on to the release candidate stage by freezing changes as early as next week.

Firefox 3.0 Beta 5 landed on Mozilla's download servers on Wednesday.

Mike Beltzner, Mozilla's interface designer, highlighted several changes to the open-source browser, including improved UI integration with the underlying operating system, performance gains from additional changes to the JavaScript engine, and an unspecified number of bug fixes and modifications for features new in Firefox 3.0, such as the full-page zoom and bookmark backup and restore.

Beltzner also called out other speed optimizing changes "to improve performance over previous releases as measured by the popular SunSpider [JavaScript] test from Apple, and in the speed of Web applications like Google [Gmail] and Zoho Office."

Beta 5's release was delayed somewhat by the discovery last week of a serious bug in the Mac version of the browser, which required fixing before Mozilla would sign off on the preview.

Updated release notes also published today noted that Beta 5 includes more than 750 changes since the rollout of Beta 4 about three weeks ago.

This beta will be the last for Firefox 3.0, Mozilla's chief engineer has said, and developers will be moving on to Release Candidate 1 (RC1). In notes from a Monday meeting that have been posted to the Mozilla Web site, the code-freeze date for the release candidate has been set as next Tuesday.

Mike Schroepfer, Mozilla's vice president of engineering, said last week that he expects Firefox 3.0 to run through three release candidates before the final version. Mozilla has targeted June for delivering the browser.

Firefox 3 Beta 4 can be downloaded for Windows, Mac OS X and Linux in 40 languages from Mozilla's site.

However, as has been its practice with every beta, Mozilla again warned casual users against using the preview. "Firefox 3 Beta 5 is a developer preview release of Mozilla's next generation Firefox browser and is being made available for testing purposes only," the release notes read.

Microsoft Office 365/Dell XPS 15 2-in-1

I’d recommend a Dell XPS 15 2-in-1 and the new Windows 10 to anyone who needs to get serious work done (before you kick back on your couch with your favourite Netflix show.)

It’s useful for office tasks as well as pragmatic labelling of equipment and storage – just don’t get too excited and label everything in sight!

The Brother MFC-L8900CDW is an absolute stand out. I struggle to fault it.

MSI GT75 TITAN

I need power and lots of it. As a Front End Web developer anything less just won’t cut it which is why the MSI GT75 is an outstanding laptop for me. It’s a sleek and futuristic looking, high quality, beast that has a touch of sci-fi flare about it.

If you’re looking to invest in your next work horse laptop for work or home use, you can’t go wrong with the MSI GE63.

MSI GS65 Stealth Thin

If you can afford the price tag, it is well worth the money. It out performs any other laptop I have tried for gaming, and the transportable design and incredible display also make it ideal for work.
