Hi

Thank you for your question and many happy returns for later this week.

This does not sound like an issue with Firefox for Android but does your phone screen work for someone else? If not, you may need to consider a new device. If it does work for them, you may find an inexpensive touch screen pointer handy - looks a bit like a pen, but with a rubber end you can use to tap the screen with.

My phone is only a few months old and it works just fine except for that minor issue with registering taps. And, I can copy/paste in other apps, just not in Firefox.

I've just tried copy/paste from Firefox to a different app on my Nook tablet; it works just fine. Clearly, the issue is with my phone and Firefox, not me.
