Disabled Add-on Fix for Firefox 47 - 56作成者: Mozilla

On May 3, 2019, an expired security certificate prevented existing and new add-ons from running or being installed in Firefox. We are very sorry for the inconvenience.

This extension will install a new security certificate and re-enable extensions and themes for Firefox versions 52 through 56. This extension hsd not been widely tested on pre-52 versions of Firefox, but have been reported to work on some machines.

If you install this extension and then upgrade to a supported version of Firefox, please uninstall this extension as it may not be compatible with updated versions.
