Excellent Add-On! Rated 5 out of 5 stars
I use this add-on all the time and it works great 90% of the time. Just a few sites that don't work right. I left a bug report on the GitHub site. Developer Sir ... please take a look. I know in your program you can specify custom field names for the user and pass to log in, but it seems that your add-on favors the user and pass fields that are brought up by the "Guess From Current Page" button. If I specify any other field than the ones guessed from that button, things don't work right. Other than that, this add-on works great!
Correct me if I'm wrong, but I have to look for the &lt;input&gt; tag, and the "name=" property???? Or is the the "id=" property ... in order to specify a custom field name (for a site that has an unusual login scheme)?
EDIT: I saw your response ... and apparently it is a Mozilla bug, and not in your code ... 5 stars :-)
Well, okay then. But perhaps in the future you should check for the response *before* posting the review. :-) But thanks for the review.
