Firefox 6 for Ubuntu 11.04/10.10

Mozilla Firefox version 6.0 stable has finally arrived. It’s available for Mac , Windows and Linux based distribution such as Ubuntu 11.04 (Natty Narwhal) or 10.10/10.04, Linux Mint, Fedora, Debian, OpenSuse etc. Firefox 6 has a some new and exciting features, e.g progress bar element of HTML 5.0, which has been already supported by Google Chrome, is now added in Firefox 6.0. So it’s a good news for web developers because they can use ‘progress’ element more effectively.

If you aren’t familiar with the rapid release cycle of the Firefox web browser or other open source projects such as Google Chrome, then you might be surprised and probably worried about the “stability and the pain of ‘version-dependencies problems’ such as plugin compatibility, usability, productivity etc”. Relax, there are some advantage too in the RAD (Rapid Application Development) approach, specifically if you are a tech savvy user; always hungry for exciting and cutting edge features, feel good in trying new things (in other words if you love experiment). These days, ‘frequent version release’ is a common attribute in some popular open source projects e.g Ubuntu and many other Linux based distributions such as Linux Mint, Fedora etc, Firefox, Google Chrome…

How to Install Firefox 6 on Ubuntu 11.04/11.04/10.04.. or other Linux based OS

#1 Download the Firefox 6 package (firefox-6.0.tar.bz2), close all the Firefox windows/tabs.

#2 Next, extract the file and execute the script (either by right click extract here followed by dragging the ‘firefox’ script from the extracted directory to the terminal or through the command).

tar -xf firefox-6.0.tar.bz2
cd firefox

#3 That’s All. Have Fun with Firefox 6.0.

firefox-6-on-ubuntu 11.04

New features in Firefox 6.0

progress-element-in-firefox 6Firefox 6 has some new and exciting features, along with a lot of bug fixes, improved speed and stability. The performance of Firefox has not been admirable (probably due to frequent crashes and slower browsing experience) on Linux platforms such as Ubuntu 11.04 or 10.10 or other ‘older versions’ or distros such as Linux Mint, Open Suse. In fact Firefox has continuously loosing its usage share on Ubuntu. One of the most exciting feature is ‘support for the HTML 5.0 – progress element’, which can be used to indicate the progress of a task. Other features includes ‘lower launch time’, improved performance on Linux/Ubuntu etc.


how to install XFCE on Ubuntu 11.04

XFCE is a most popular lightweight desktop environment for Unix like operating systems such as GNU/Linux, FreeBSD, NetBSD, Mac OS X etc. It is a free and open source software, consumes less resources then other desktops available for Ubuntu 11.04 (Natty Narwhal) – such as Gnome 2.*, KDE etc. Xfce desktop comes along with some applications installed by default – e.g Thunar (File Manager), Midori (Web browser), Mousepad (Text Editor); that is very simple to use and provides pretty fast experience without consuming a lot of memory or other resources.

Why should you try XFCE ?

Ubuntu 11.04 uses ‘Unity’ desktop by default but if you are running ubuntu on a older hardware/computer or got tired with the slow performance of other desktops then Xfce is the right desktop for you.

Xfce 4.8 is the latest stable version available, released in Jan 2011. You can install it either from command line or Synaptic Package Manager, and it works not only for ubuntu but also for other Linux distros such as Linux Mint, Fedora etc.

Avast Antivirus for Ubuntu 11.04/11.10

Antivirus software for Ubuntu Users – is it optional ?

Ubuntu 11.04 (Natty Narwhal) or 11.10 (Few alpha versions has arrived, the stable will be released after few months) or 10.10 or any Linux based distributions are very less prone to virus attacks or malwares, spywares (or any similar *wares). The reason is pretty straight forward – First Linux based operating systems are highly secure and the second reason is that Microsoft Windows (XP, Vista, 7 ..) has been the targeted systems for crackers / hackers or malicious programmers (may be due to the fact that most of the common users uses Microsoft Windows operating system).

Therefore, in general, you don’t need to install any antivirus software on Ubuntu; it’s OK!

I have tried avast antivirus on Window 7, it was really good, and its basic version is free for Windows as well as Linux based OS such as Ubuntu!

Android SDK for Ubuntu 11.04/10.10/11.10

Ubuntu – The most popular Linux distribution for desktop users (with an exponential growth in past few years) and Android – one of the most popular mobile operating system, also based on Linux kernel; developed by Google Inc.

Ubuntu 11.04 (alias : Natty Narwhal) or older versions such as 10.10 (Maverick Meerkat) or 10.04 (Lucid Lynx) is now becoming the dominant choice for programmers and web developers probably due to the features (cool desktops (window manager, e.g Gnome, KDE..), open source applications, tools, no licensing cost…) and flexibility available on Linux based operating systems. Android stable version 2.3.5 (Gingerbread) was released a day ago.

Android SDK

Do you want to develop android apps using Linux based distributions, then this post will explain you about installing Android SDK (Software Development Kit) on Ubuntu, despite of that you can apply the same procedure in installing android sdk on other Debian based GNU/Linux OS such as Linux Mint.

Before diving into installing steps for android sdk in Ubuntu 11.04, I assume you have already installed –

  1. JDK (Java Development Kit)
  2. Eclipse IDE

If my assumption is wrong (I mean you haven’t installed the Java SDK and Eclipse IDE) , then follow these link :

how to install JDK on Ubuntu 11.04
how to install eclipse IDE on Ubuntu 11.04

After installing those packages, come back here to proceed.

How to Install and Configure Android SDK with Eclipse IDE

Now, you can install Android in two simple steps :

step #1 : Download and install the android package(s).

Download SDK Starter Package
Then extract the package(s) either by right clicking -> extract or do it from Terminal :

Open Terminal (CTRL+ALT+T) and move on (use cd target_directory) to the directory where you have downloaded the packages.

tar -xf android-sdk_r12-linux_x86.tgz


Android SDK and AVD Manager will be started with the above command,

Android SDK and AVD Manager
now you just need to select the packages (first one you get after expanding Android Repository, is probably mandatory and select the SDK platform version for your targeted device, documentation, sample apps…or any third party Add ons if required) you want to install, then click on ‘Installed Selected’ button; wait for the Download/Installation to complete. (Since the selected packages will be fetched from Internet you need an active internet connection during installation procedure)

step #2 : Install and configure the ADT (Android Development Tool) plugin

start Eclipse and go to Help > Install New Software, then click on Add. Enter the ADT Plugin in name and the following address (in case of any problem, try http instead of https (The secure version of http protocol).. or simply click on archive and locate the manually downloaded ADT plugin file ) as Location.



Then click on Next -> select developers Tools -> Next -> Finish.

Now, it’s time to configure ADT Plugin, Click on Window -> Preferences -> Select Android in left panel and locate the Android SDK directory, and hit Apply/OK.


That’s all.
