Although it's Tuesday, it's not "Patch Tuesday", which means we shouldn't expect any updates from Microsoft, but the software giant is rolling out patches none-the-less. The updates are across a broad spectrum of platforms too -- Windows 7, Windows 8, Windows Server, and even Windows RT are included in this update.

Curiously, many of the Windows updates are listed as "non-security". The company generally only pushes out-of-cycle updates when there is a major security flaw that cannot wait for the next month. In the case of today's patches, many are listed as a fix for "issues in Windows".

If your browser has been taken over by an aggressive addon then you can try the standard routes to remove it (the "Manage Addons" dialog in IE, for instance). These can be confusing for beginners, though, and may not always work, so avast! has developed a custom Browser Cleanup tool as a simpler alternative.

The program is portable, a compact 1.75 MB download which runs on Windows XP, 7 and 8, so it’s generally convenient to use. It supports IE, Firefox and Chrome, and on launch checks each of these to evaluate your browser addons.

Smartphones running Firefox OS are slated to start shipping by mid-year. Twitter will be there with them. In a brief announcement, Manuel Deschamps of Twitter stated that "When those devices begin to ship, Twitter for Firefox OS will be available in the Firefox Marketplace".

He also assures us that the app will rival that produced for other mobile operating systems. It will contain Home, Connect, Discover and Me tabs, as well as be able to search and compose tweets -- that last one is rather important to the whole concept of Twitter.

Moonchild Productions has launched Pale Moon 19.0 and Pale Moon x64 19.0 for Windows. Pale Moon is a customised build of popular web browser Firefox, with the developer making no attempt to keep pace with Mozilla’s six-weekly development cycle in favour of applying security updates and concentrating on delivering improved performance.

This release marks the first major update since Pale Moon 15.0 -- based on Firefox 15 -- was released last August, but while Pale Moon 19 utilizes the brand new Gecko 19 engine found in the latest version of Firefox, don’t expect to see all the functionality in Firefox 19 making an appearance here.

Seventeenth in a series. The Windows 8 app store is picking up pace again. New apps this week almost doubled in comparison to last week. A total of 1,049 new apps found their way into Windows Store -- of which 826 were listed as free to install and use and 224 as paid apps. It will be interesting to see if this is the beginning of an uptick in terms of new apps in the store or if things will dry off again in the coming weeks.

Microsoft did update a couple of first-party applications this week. Just in is the Skype update, which enables Windows 8 users to transfer files using the client, a feature that has been an integral part of the desktop app for a very long time.

Google has announced the release of Chrome 25 to the Stable Channel for Windows, Linux and Mac, and as revealed in the beta, this release features a major change in the way extensions are handled.

In particular, the previous support for the automatic and silent installation of extensions will now be disabled by default, as apparently Google has noticed that this feature "has been widely abused by third parties to silently install extensions into Chrome without proper acknowledgment from users". We could argue Google really should have predicted that in the first place, but at least it's seen the light now.

Mozilla has released Firefox Beta 20.0b1, the first public beta of a landmark release. Like its predecessor, Firefox 19 FINAL, which debuted the new inline PDF viewer, version 20 looks set to unveil another major new feature to the Firefox armoury: a redesigned, panel-based download manager.

Version 20 also includes a major refresh of the Developer toolbar, providing tweaked and redesigned access to all of the major components, plus an option to view the tools in a separate window. A new Javascript benchmarking tool has also been added.

Parental controls software is normally bulky, complex, and the kind of application which can take some considerable time to configure. There may be lots of files to install, resident components which must always be running in the background, user profiles to create, content filters to customize, and the list goes on.

If your child protection needs are simple, though, you may not have to worry about any of this, as DNS Angel can provide a reasonable amount of protection with a single click.

Mozilla has released Firefox 19.0 FINAL for desktop. There are only two notable new features in this new build, but after months stuck in beta, Mozilla has finally enabled its built-in PDF viewer, which allows users to view PDFs directly in the web browser without having to use a third-party viewing utility.

The other major new feature is a security one, with the Firefox Awesomebar now set up to alert users if the default search provider has been changed. In the meantime, Firefox 19.0 for Android -- due for release imminently -- will introduce support for themes, plus lower its system requirements to extend its reach to as many as 15 million more smartphones.

No, I did not say that Internet Explorer is the walking dead. However, Microsoft's web browser is partnered with the show's creator, Robert Kirkman, to bring the original comic book series, "Thief of Thieves", to life on your computer. In other words geek nirvana -- a comic book and a computer. This ranks up there with the Lego Android from last week.

Microsoft's Steve lake says this will be "an interactive online game based on the comic book series from Robert Kirkman and Skybound, his imprint at Image Comics. The site is a showcase of the new features in Internet Explorer 10, including full multi-touch capabilities and HTML5 support".

Sixteenth in a series. Windows Store's slow but steady application growth continues this week with the addition of 610 new apps in the US store. This brings the total listed to 28,665.  Of those, 22,101 free and 6,563 paid. It is not clear why there is one application missing when you add free and paid apps.

The growth is slowing down if you look at the recent performance. Two weeks ago, 970 new apps were listed in Windows Store, one week ago that number dropped to 773, and this week we see another drop to 610 new apps. It will be interesting to see if the downwards trend continues or if there will be a recovery in the coming weeks.

Opera's decision to change rendering engines means three of the top five browsers will use Webkit. Internet Explorer stands alone, and that is the wrong place to be. In September 2009 post "Microsoft should dig deep into Webkit to keep Google from Framing IE", I suggested radical change, which unsurprisingly was ignored. Since, Chrome usage share grew from 2.9 percent in August 2009 to 17.84 percent in January 2013, according to Net Applications. Meanwhile, IE share fell from 66.97 percent to 55.14 percent.

But the real battleground, and where upstarts gobble up territory, is mobile -- yeah smartphones and tablets. While the category accounted for just 11.8 percent browser usage share in January, the majority is Webkit -- 61.02 percent just for Safari. Internet Explorer: 1.34 percent, or less than Chrome (2.02 percent). Android browser is 21.46 percent. As I expressed three-and-a-half years ago: "Microsoft should answer WebKit for WebKit, by releasing a new browser based on a new rendering engine; put on the IE brand and ship it for desktop and mobile". There's still time, but fast running out.

Mozilla announced back in October that it would release a Metro Modern UI version of Firefox. At the time, the company released a "preview" version that was code named "Elm" which was an offshoot of the Nightly builds that the company produces for those users who wish to live on the bleeding edge of technology.

The day has finally arrived where that test build has graduated to an actual Nightly build. Yesterday evening Mozilla's Asa Dotzler announced that "preliminary Metro Firefox development work arrived at mozilla-central, the source code repository that feeds the Firefox Nightly channel".

As far as web browsers go, Opera never seems to get enough love. But it has a dedicated following of avid users who seem suddenly to appear whenever you say something bad about the software. Now that following has grown, and Opera plans to reward them with a new engine.

Today CEO Lars Boilesen proclaims a milestone: "On the final stretch up to 300 million users, we have experienced the fastest acceleration in user growth we have ever seen". While that is certainly a big step for the company, and worthy of a pat on the back, Opera browser still remains far behind its competitors.

QR codes can be a very convenient way to convey URLs, images, text or other information to anyone who scans them with a compatible smartphone, or other mobile device.

And it’s just as easy to create QR codes for yourself. You don’t need to buy some complex package, in fact you don’t have to spend any cash at all: QrCodeR is an excellent Firefox extension which will create all the codes you need for free. (Although the author will happily accept -- and probably deserves -- donations, if you’re feeling generous.)
