You may use this command to downgrade firefox from version 3 to version 2,
$ sudo apt-get remove firefox-3.0 && sudo apt-get install firefox-2
The already installed plugins won’t work for firefox 2. So you have to rename your firefox settings folder to other name by executing:
$ mv .mozilla mozilla.downgrade
I have just read this, it’s a programming ratings table for 2008. At least this will helps the programming stakeholder to choose which programming language should he use while building a project.
From the table, it can be concluded that open source programming language is more preferable than closed source and commercial programming language.
It proves that programming language for the futures is the free and open source programming languages.
