The Mozilla developers have released an add-on for the Firefox browser to fix the problem that older add-ons are disabled in the browser. <\/p>\n<p><!--more--><\/p>\n<h2>The add-on bug in Firefox<\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" alt=\"\" src=\"https:\/\/vg05.met.vgwort.de\/na\/00ae5ca382974777b2dd7ac49010d710\" width=\"1\" height=\"1\">On Saturday, May 4, 2019, Firefox is causing issues with add-ons on all platforms and in all versions. Some already installed add-ons were suddenly disabled. The background was an expired certificate that developers must use to sign certain add-ons. Starting with Firefox version 57, only those addons based on WebExtension APIs will work. What was planned as a security feature bricked many addons due to the expired certificate. <\/p>\n<p><img decoding=\"async\" title=\"Firefox: Download fehlgeschlagen.

Later they released updates for Firefox version 66.0.4 and 66.0.5 to fix the issue. For older Mozilla versions there was no update available to reactivate add-ons.<\/p>\n<h2>Add-on fix in older Firefox versions<\/h2>\n<p>Mozilla has now released the Firefox add-on Disabled Add-on Fix for Firefox versions 47 &#8211; 56. This extension again activates the extensions that were deactivated on May 3, 2019 for Firefox versions 47 &#8211; 56 by the expired certificate. This extension installs a new security certificate so that the extensions and designs for Firefox versions 47 to 56 can be reactivated. <\/p>\n<p>Please note: If you install this extension and then upgrade to a newer version of Firefox (version 57 or higher), please uninstall this extension as it may not be compatible with updated versions.
