I want to delete some form data in Firefox. At Tools > Clear Recent History... there is option to delete all form data, but I do not want to do that. I expected that highlighting the entry I want deleted and pressing delete button would delete the it, but that does not work.


To delete saved form data in Firefox on a item-by-item basis:

  • Highlight what you want to be deleted in the drop-down.
  • Make certain that the drop-down remains on the screen.
  • Press Shift+Delete to remove that entry.

Note: If you click an item from the drop-down, it populates the input box and the drop-down disappears. If you highlight the text in the input box and press shift+delete, the only result is that the input box is cleared. Doing this does not delete the saved form data.

  • This still works (as of 2019). To be clear about the process: On the webpage with the form, first clear the form field. Then you can open said drop-down by clicking again into the form field. – Qw3ry Jul 8 '19 at 7:27

Use the "Form History Control" extension. Can automatically cleanup just the unwanted formdata.


In Firefox Mobile you can, when the the dropdown appears you can sleect-and-hold-and-swipe-left.
