Grammarly for Firefox not working.

I use Grammarly add-on in Firefox, and it was working fine before. There was an update to Firefox 66.0.3 for Mint and since that update the Grammarly is no longer accepted. When I try to add it again either through Firefox or directly, via Grammarly, the system tells me that I should check my connection (Firefox) or that the add-ons cant't be installed as they appear to be corrupt.

Hi Neilan, most likely it's not a problem with your connection, it's everyone's connection.

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:
