This Firefox Extension worked great for a long time. It now seems to be non-functional in Firefox. I've done everything I can think of including confirming that it was active and even uninstalling and reinstalling it. But nothing fixes it in Firefox 95.0.1 on my Windows PC. The button stays Greyed out on every website including ones where it used to work great (Amazon, Ebay, etc...). Now when I click on it, it opens a blank text box and the Extension itself is always grey. It never turns orange. My other extensions all work fine, including the similar RetailMeNot extension.
