Opera has unveiled its secret project, which it was hoping would “change the web”. With Opera 10, the company is planning on introducing new technology called Opera Unite.

Opera Unite allows users to share files and host websites right from in their browser.

“This technology is a radical first step towards addressing what I call “the Internet’s unfulfilled promise”, which is about our ability to connect with each other and participate meaningfully online—on our own terms, and without losing control of our data” writes Lawrence Eng, Opera Software Product Analyst.

More information and early download links can be found on the Opera Unite homepage.

Microsoft has started a campaign that will donate the financial equivalent of eight meals to the Feeding America network for every complete download of Internet Explorer 8.

The Browse for the Better campaign runs from June 10th till August 8th 2009. Microsoft will be donating $1.15 per download, to a maximum of $1,000,000.

The Feeding America network distributes close to 1000 tones of food per year to more than 25 million low-income individuals in the United States.

More information on how you can help can be found on the Browse for the Better campaign website.

Apple has released a press release stating that Safari 4 has been downloaded over 11 million times in just 3 days.

Breaking these down, there were 6 million downloads for Windows and 5 million downloads for Mac OS X.

To compare, Firefox 3 was downloaded 20 million times in 7 days, so the numbers from Apple seem quite reasonable.

Apple claims that Safari 4 is “nearly eight times faster than IE 8 and more than four times faster than Firefox 3. Safari quickly loads HTML web pages more than three times faster than IE 8 and three times faster than Firefox 3”.

Safari 4 can be downloaded for Windows and Mac from the Apple Safari website.

Mozilla has pushed out another update to Firefox, taking it to version 3.0.11. The latest release fixes 9 security vulnerabilities, 4 of which as rated as critical, along with a large list of other bugs.

Microsoft is proposing to release Windows 7 E in the European Union (EU), a version of Windows without Internet Explorer.

The move is aimed at pleasing the European Commission regulators who are currently taking action against Microsoft over it’s bundling of Internet Explorer with Windows.

If agreed upon, Microsoft will completely remove Internet Explorer from Windows, and not just hide the browser like is currently possible. Despite this move, manufactures are still likely to release PC including Internet Explorer.

We will let you know Microsoft’s final decision when it is made.

The European Union (EU) is set to ask major PC vendors for evidence that Microsoft pressured them to oppose the EU’s plan to give consumers choice when they first start Windows.

Questionnaires have been sent to PC makers seeking information about their communications with Microsoft.

“Microsoft hasn’t seen the commission’s questionnaire and doesn’t pressure any PC makers to oppose the ballot-screen remedy”, said Microsoft spokesman Jesse Verstraete in Brussels.

It appears Firefox 3.5 Release Candidate 1 is now expected at some stage this week. Nightly builds of the browser now include the RC1 tag, suggesting that we will see a release some time this week.

Current early Windows builds weigh in at 7.6MB and run on Windows 2000 all the way up to Windows 7.

On the outside, the browser doesn’t appear too different from Beta 4, but there are plenty of bug fixes that have gone in under the hood. “Even before shipping the RC, we’ve managed to find a number of issues that needed fixing,” said Mike Beltzner, the director of Firefox.

The final 3.5 release is still expected before the end of the month, and we will let you know as soon as the release candidate is released.
