Beta 6 continues to be the last fully-fledged Beta Build of Firefox 4.0 offered to early adopters, but testers can now also grab a preview of Firefox 4.0 Beta 7.

Mozilla has essentially made available the Release Candidate of the seventh Beta for Firefox 4.0, a nightly build, served to the Beta community through the browser vendor’s FTP servers.

Almost two months have passed since Mozilla launched the previous Beta, and in the process the Firefox 4.0 development was postponed considerably.

However, Firefox 4.0 Beta 7 will certainly be worth the wait. Testers will be able to notice a consistent increase in JavaScript performance, a boost in hardware acceleration and better HTML4 support.

Mozilla highlighted some of the changes that Firefox 4.0 Beta 7 will bring to the table, such as: More »

Yesterday, Apple released Mac OS X 10.6.3, the third incremental update to its Snow Leopard operating system, delivering bug fixes and enhancements, as well as addressing a number of security issues discovered since the release of OS X 10.6.2 in November. This news piece goes deeper into the changes delivered with this update. The security side of 10.6.3 will be detailed in a different article later today.

Over at its Support Downloads area, Apple mentions key 10.6.3 improvements such as a more reliable QuickTime X. Apple’s player has also been updated with compatibility fixes, according to the summary of changes. Other compatibility issues have been addressed with OpenGL-based applications, Apple stresses. The Mac maker continues to list changes like improved performance of Logic Pro 9 and Main Stage 2 when running in 64-bit mode, improved reliability of 3rd party USB input devices, and a few others.

However, via a Support document posted in the section with the same name, Apple talks “About the Mac OS X v10.6.3 Update” more broadly. Before users attempt to do anything, the Cupertino-based Mac maker advises customers to back up their systems. Although the Mac OS X built-in Time Machine utility is probably the best choice to accomplish the task, there are several other tools that allow them to achieve the same results. More »

Last time I installed OS X on my Mac, I did an Archive and Install and selected the “Preserve Users and Network Settings” option. However, people might forget to check if the “preserve users …” option is selected and will end up with a new OS X installation on their Mac but with none of their files. Although you might think that all your data is lost, you could not be more wrong.

Other people may also delete a user account on their Mac and later remember that they had some important files on that user’s home folder. Do you think their data is lost? Think again. You can actually “undelete” a user’s account altogether.

Apple has a number of support documents that explain how you can easily get your data back in case you end up in one of the above mentioned situations and this is how easily it can be done.

You have to remember one thing: if you used the “Delete immediately” option, you will not be able to use the steps below to recover your data. Nevertheless, you can still recover at least some of it if you use a third-party recovery tool.

Restore a user’s account after an Archive and Install (Mac OS X 10.3 to 10.5)

If you are using Mac OS X 10.5 or later, these are the steps Apple says you have to follow to recover your entire Home folder (the one you had before the installation):
