Ive noticed on Firefox mobile, I'm unable to click any post buttons. In particular Ive noticed it when I would tap a button to upload a file (like a photo). While this happened on Facebook and Instagram, it also happens on my friend's personal project site. This is specific to Firefox on Android. Happens whether or not I toggle Desktop mode. It simply does nothing when I tap any buttons associated with uploading a file. The button does not visually flash or anything. Nothing at all happens. Ironically I can't upload an image on this very form because of it, though this button does highlight like I pressed it.
