Hi

This does not sound like an issue with Firefox for Android, but I will try to help.

When you are looking at you email and have selected one, you should see a small trash can icon at the top of the screen. Tapping that will send the email that you are looking at to your trash folder.

This answer suggests that it is necessary to open and view each email before it can be deleted. That is way to tedious. There should be a way to delete an email without opening it. Like clicking on it or double tapping or sliding it to a disposal icon, etc. I have tried those procedures but they do not work so I am still stumped and looking for an easier way.

As mentioned previously, this does not sound like an issue with Firefox for Android. I recommend that you contact the GMail support team for help with this issue.
