Some basic instructions would be helpful. Form Filler only inserts random (dummy?) info, even though I have edited the custom fields. I'm sure it's something simple, but I can't figure it out.

I haven't used it much yet, but it seems to do exactly what I hoped it would.

Its really saving my time and time is money. I just missing a confirmation code that should receive to confirm an account while using random emails.

The only downside it's that I didn't manage to setup my forms, only works as a dummy test. If you make it to work with our own data would be great!

This add-on was the only reason that I sometimes had to switch to Chrome, because one of my apps has a very long form fields that I need to fill with dummy data and this add-on is the only one I found does the work with no issue. I got surprised when I saw it's available here on Firefox now.
Kudos to the developer.

Tested quite a few auto-fillers.. some don't work as claimed, some require tedious configuration, this one just works.
Thanks!
