Firefox 4 is out and is much better, faster, sleeker and safer ! Here’s how you can install or upgrade your Firefox in Ubuntu to Firefox 4. Type the following commands into your Terminal.
Step 1 : Add the official Mozilla Firefox Ubuntu PPA by
sudo add-apt-repository ppa:mozillateam/firefox-stable
Step 2 : Update the repository.
sudo apt-get update
Step 3 : Then, install Firefox 4 package.
sudo apt-get install firefox ubufox
Note : ubufox adds Ubuntu-specific modifications to Firefox.
That’s it !
The mozillateam is the group who maintains Firefox packages for Ubuntu. The stable release is in firefox-stable. Note, that this will upgrade your current Firefox version to 4.0. The packages in this PPA will not be parallel installable with the packages in the official Ubuntu archive. Installing Firefox from this PPA will provide Firefox 4 in English. For other languages you’ll have to install an extension.

Changing DNS server settings
I think that it’s cool and ‘geeky’ to be able to launch your favorite and frequently used application just the way you launch regedit, cmd or services.msc from the Run dialog box or even from the Command Prompt. In this post, I am going to tell you 3 methods to do this. The first two methods can be used only to launch executable files where as third method can be used to launch any file or directory.
1. Using Add2Run utility

Why can’t I uninstall certain softwares ?
I’ve seen in many forums that users ask for a solution on how to uninstall certain softwares. Many of my friends too call me and ask what should I do if I cannot uninstall a software ? First, we must know why it cannot be uninstalled using the bundled Uninstaller or from Control Panel using Add/Remove Programs. The reason might be that, the software files might have been corrupt OR the PC could be infected with virus OR the software installed is a rogue software OR even the OS files could have been corrupt OR the registry keys belonging to the software might be corrupt.
What should I do ?
The first thing, you must do is try uninstalling the software using the ‘usual way’. By usual way, I mean using the Add/Remove Programs option or using the Uninstaller that came with the software. One thing that you require is patience. It might take long time or your system might be non-responding for a few seconds. The uninstaller might ask you to restart your PC too. Do it as it says.
