After upgrading to Quantum, I'm unable to install any add-ons from https://addons.mozilla.org.

I've made sure I'm using the latest version of Firefox.

When I find an add-on I want to install (having checked it's compatible with Quantum), the 'Add To Firefox' button is always disabled and below is a red banner saying: "You need to download Firefox to install this add-on."

Does anyone have any suggestions?

Edit - I've also made sure there are no active add-ons.

Thanks

Thanks philipp, that worked. Appreciate your help (and the quick response).

As an aside, even when the button was disabled, I found I was able to download the add-on xpi manually.

Right-click the disabled "Add To Firefox" button, and select "Save Link As". Then drag and drop the downloaded xpi file on to Firefox to install it.
