The same with any other day, Mr. Google has once again help me in finding solution to my problem. This time downgrading my Firefox browser. Below are the steps that I followed on one of the blogs that have help me.

Important Reminder: Make sure you are really using Ubuntu 11.04(Natty Narwhal ... :-) ). Also if you are having trouble installing add-ons like Firebug, Selenium IDE, etc. on your newly downgraded Firefox try deleting the language pack that keeps on popping-up everytime you open Firefox along with the previous add-ons and extensions installed on Firefox5

Step 1: Edit your software sources to add Maverick

1. Open your sources.list file:
   

   sudo gedit /etc/apt/sources.list

2. Add the folowing three lines:
   

   # Maverick, used for firefox and firefox-branding  deb http://ftp.iinet.net.au/pub/ubuntu/ maverick main  deb http://ftp.iinet.net.au/pub/ubuntu/ maverick-updates main

3. Save and close the file

Step 2: Pin the packages firefox and firefox-branding

1. Create the pin file for firefox:
   

   sudo gedit /etc/apt/preferences.d/firefox

2. Add the following:
   

   Package: firefox Pin: release n=natty Pin-Priority: -10  Package: firefox Pin: release n=maverick Pin-Priority: 900

3. Save and close the file.
4. Create the pin file for firefox-branding:
   

   sudo gedit /etc/apt/preferences.d/firefox-branding

5. Add the following:
   

   Package: firefox-branding Pin: release n=natty Pin-Priority: -10  Package: firefox-branding Pin: release n=maverick Pin-Priority: 900

6. Save and close the file.

Step 3: Check your apt policy to make sure it worked

1. Update your apt cache:
   

   sudo apt-get update

2. Show the apt policy for firefox:
   

   sudo apt-cache policy firefox

   
   Sample output:
   

   sudo apt-cache policy firefox firefox:   Installed: 5.0+build1+nobinonly-0ubuntu0.11.04.2   Candidate: 3.6.18+build2+nobinonly-0ubuntu0.10.10.1   Package pin: 3.6.18+build2+nobinonly-0ubuntu0.10.10.1   Version table:  *** 5.0+build1+nobinonly-0ubuntu0.11.04.2 900         500 http://ftp.iinet.net.au/pub/ubuntu/ natty-updates/main i386 Packages         500 http://ftp.iinet.net.au/pub/ubuntu/ natty-security/main i386 Packages         100 /var/lib/dpkg/status      4.0+nobinonly-0ubuntu3 900         500 http://ftp.iinet.net.au/pub/ubuntu/ natty/main i386 Packages      3.6.18+build2+nobinonly-0ubuntu0.10.10.1 900         500 http://ftp.iinet.net.au/pub/ubuntu/ maverick-updates/main i386 Packages      3.6.10+build1+nobinonly-0ubuntu3 900         500 http://ftp.iinet.net.au/pub/ubuntu/ maverick/main i386 Packages

   
   The line you are most interested in is "Candidate".
   This indicates the package that apt ranks as the installation candidate.
   
3. Repeat this check for firefox-branding
   

   sudo apt-cache policy firefox-branding

Step 4: Install firefox 3.6

1. Remove firefox 5.x:
   

   sudo apt-get remove firefox

2. Install firefox 3.6:
   

   sudo apt-get install firefox

And you're done. Enjoy your outdated version of Firefox!

$ sudo mkdir -p /opt/oracle

$cd /opt/oracle

$sudo unzip /path to /downloads/instantclient-basic*.zip

$sudo unzip /path to /downloads/instantclient-sdk*.zip

$cd instantclient_11_2

$sudo ln -s libclntsh.so.11.1 libclntsh.so

$LD_LIBRARY_PATH=/opt/oracle/instantclient_11_2

$export LD_LIBRARY_PATH

4.) Go to your home directory and do
