I need to load a previous version of Firefox.

Posted

The current version disabled my Ghostry and AdBlock making several of the websites I normally visit regularly almost unusable.

Hi flybob, this wasn't caused by an update. Sort of the opposite. A critical certificate used in verifying add-on signatures expired, so you need a hotfix to install, enable, or update most add-ons. More info in this article:

Add-ons disabled or fail to install on Firefox

UPDATE: Firefox 66.0.4 and 60.6.2esr are now available with the new certificate needed to solve this problem. See: Update Firefox to the latest release.
