We are working on updating our Firefox plugin and plugin listing. We hope to have this done in the next few days.
In the meanwhile, you won't be able to install Kopernio for Firefox, although Chrome and Edge will work as normal. If you have already installed Kopernio in Firefox, you don't need to do anything - Kopernio will continue as normal.
