Can't install any add-ons - "You need to download Firefox to install this add-on.". Firefox is latest version.
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.
