There is an extension to fill automatically form on certain domain name or URL, and also submit it, without clicking on the extension button? I searched but all extensions require the user to click or doesn't have the submit option. I found this extension for Chrome that does this but it's not available for Firefox and have some issues with the automatic submitting forms: https://chrome.google.com/webstore/detail/autofill/nlmmgnhgdeffjkdckmikfpnddkbbfkkk
