I want to downgrade to v21, where can I find it?

more options

The avast! easypass toolbar vanished once I installed v22. I was wondering if I could be provided with a link to solve my problem.

On another note will this issue be corrected. I know that it's essentially avast that will have to do some tweaking, but has anybody heard anything about support with v22. I don't want to leave my browsers security at risk.

Known vulnerabilities in Firefox 21

If you want to downgrade anyway, download firefox 21 here

Go for Clean reinstall

  1. After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
  2. Delete the Firefox installation folder, which is located in one of these locations, by default:
    • Windows:
      • C:\Program Files\Mozilla Firefox
      • C:\Program Files (x86)\Mozilla Firefox
    • Mac: Delete Firefox from the Applications folder.
    • Linux: If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see Install Firefox on Linux. If you downloaded and installed the binary package from the Firefox download page, simply remove the folder firefox in your home directory.
  3. Now, go ahead and reinstall Firefox
