eature Request / Usability Issue: Ability to directly "Save" (overwrite) edited local PDFs instead of only "Save As"

Hi, When editing or annotating a local PDF in Firefox's built-in viewer, pressing Ctrl + S (or clicking the save icon) only triggers a "Save As" prompt instead of saving changes directly to the original file. Manually selecting the source folder and confirming the overwrite dialog every time adds a lot of friction to reading and annotation workflows. Could we get a native "Save" (in-place overwrite) option alongside "Save As" for locally opened PDF files? Thanks!
