They literally just mean things like filling out forms. Implicitly or explicitly you have to give Firefox permission to store and reproduce the text you type in this very textarea so that it can submit the form for you.
But I agree with you that this should not require specific legal language. However, I point out that most other browsers have already added that same language, or something similar, to their own ToS. As have programs such as Microsoft Office. If you cannot use Firefox then you cannot use any of them either.
