I use Roboform to submit to directories, fills all fields and even categories most of the time (the way I have it set up). All filled out perfectly as well.
Yeh I've used roboform in the past, and while it's okay for just submitting to a few directories, if you want to submit to lots then it quickly becomes quite laborious. The whole submission process is a little slow, and it takes time for the webpages to load, and you need to maintain your own directory list etc etc. What SubmitEaze does, and I would imagine others, is pre-load several directories in advance of the current one you're submitting to, so as soon as you press the submit button it displays the submission form for the next directory. Tis the mutts nutts if you're into directory submissions.
Not at all. I get a list then use linky extension to open all the links (all are already loaded then), hit "submit" Alt+N hit the profile needed to fill and then hit submit. Works with any directory script too.
