User reviews

The Web Developer Form Filler Firefox add-on is praised for saving time and efficiently filling complex forms, benefiting both developers and general users. However, users frequently note the inconvenience of losing saved form data after closing Firefox, absence of export/import features for saved data, and issues with shortcut keys. Additionally, managing numerous saved entries is hindered by missing filter and sort options.

  • Very useful for web developers testing forms and also for general users filling repetitive forms.
  • Easy to use and effective in filling forms accurately.
  • Provides a comprehensive set of features for form filling.
Cons
  • All saved form data are deleted upon closing Firefox, requiring re-entry each session.
  • No visible option to export or import saved form data, limiting syncing capabilities.
  • Shortcut hotkeys do not work properly for some users.
  • Lack of filtering or sorting options for saved form entries makes managing many entries difficult.
