Hold up...Firefox is holding all text input in memory, even after the text is gone via tab close / deletion?

That seems odd...generally handwaving for clarities sake: privacy and performance

It may well not be holding on to it. The text may just be in freed heap memory space that hasn't been overwritten yet.

Memory pages allocated to the firefox process typically stay as part of its working set, so they get dumped along with everything else.

You can reopen closed tabs and windows from the History menu. It will restore the state of forms, so that form state is retained somewhere (presumably memory).
