The Firefox for Android add-ons section (yes, I made sure I was in the 'for Android' add-ons web address, as opposed to the 'desktop add-ons' web address) is saying "You'll need Firefox to use this extension" and not allowing me to install add-ons as the page employs a download firefox link that leads to an "Open" button in the Google Play Store, as I already have Firefox installed. I have tried many different add-ons to test if the issue is isolated to a single add-on and to test if it is an add-on compatibility issue, and it seems to be a consistant issue with all add-ons. Yes my underlying operating system (Android), and the Firefox for Android app are both up-to-date with the latest versions. I have located the Firefox support page labeled "Unable to install add-ons (extensions or themes)" and was able to work through the the list of potential issues and their solutions, to determine that every item on the list was either inapplicable or not the problem/solution. What am I missing?
