How do I downgrade a package?

  • 772

I just upgraded to Firefox 5 to find out that Selenium does not work on it. I'd like to downgrade to Firefox 4 but haven't found a way to do this.

How do you downgrade to Firefox 4 on 11.04?

Thanks in advance.

  1. Best Answer

    1. Start "Synaptic Package Manager"

    2. Type in "firefox" in the quick filter and highlight it in the search result (the one w/ the green box next to the package name indicating that it is already installed on your computer)

    3. Select from the menubar "Package" -> "Force Version"

      Package Force Version

    4. Select 4.0 from the dropped down list "4.0+nobinonly-0ubuntu3 (natty)" and click "Force Version"

      Force Version

    5. "Apply" changes

      Apply

  2. you can install firefox with repository .

    and download firefox from firefox.com and run it . 

    Download Firefox from the Firefox download page to your home directory.
Open a Terminal and go to your home directory: cd ~
Extract the contents of the downloaded file:tar xjf firefox-*.tar.bz2
Close Firefox if it's open.
To start Firefox, run the firefox script in the firefox folder.

    ~/firefox/firefox

    Firefox should now start. You can then create an icon on your desktop to run this command.
