AutoFill plugin/extension which works for all browsers?

Question

I am currently thinking of writing an AutoFill plugin/widget which will take my personal data such as First Name, Last Name etc from a file/javascript and will automatically fill it in web page form. I have read till now to build a plugin which works for all browsers, I have two options:- 1) To make a Jquery UI widget 2) To make a NPAPI plugin

Is there any other easier method to develop an autofilling plugin, and which option to take i.e. NPAPI plugin or Jquery widget ? Thanks

Answer 1

Neither of the two options you mention will allow you to automatically fill in your personal data on all websites.

You'll want to write a browser extension (which are different from plugins). As you want to target multiple browsers, you may want to look into frameworks which make that easier, like crossrider.
