Hello can we add firefox for android and also b2g on input also would it be hard to add thunderbird for products to give feedback about

We have Firefox for Android: https://input.mozilla.org/feedback/android and Firefox OS already: https://input.mozilla.org/feedback/fxos We only capture feedback for products we're actively analyzing feedback for. No one has requested we add Thunderbird as a product on Input so far and there's no "Submit feedback" in the Help menu in the Thunderbird product. If the Thunderbird developers want to collect feedback for Input, we should open up a bug for that specifically. For now, I'm going to close this out as WORKSFORME.

Hello will can I suggest we add a link to the other products on https://input.mozilla.org/en-GB/feedback as would be good for them on that like a main page with a link to each page

Yup! That's covered in bug #970325. We're close, but not quite there, yet.
