Don't waste your time with it Rated 1 out of 5 stars
It worked without problems with my last Firefox 3.5. But since FF 4 I am not able for instance to export my profiles. You simply get a blank file. This and other problem are known for a long time but no-one cares. So this add-on looks abandoned to me.This review is for a previous version of the add-on (0.9.8.1).
Sorry you've been having trouble. I'll be looking into the export feature.
I'm compiling a list of things for fixing in Autofill Forms. Can you let me know what other problems you have had? Feel free to email directly to firstname.lastname@example.org Thanks!
