Mouse to the top of its window, hold down the right button and move it out of the way. You may also be able to reduce its size via its options.

This doesn't solve the problem, that's what i'm forced to do now. Move around the touch keyboard. Firefox should have the same functionality as Edge and Chrome. When the touch keyboard is blocking, the page should shift up, so you can see the input field.

If this feature doesn't exist in a setting, maybe it should be suggested to firefox.
