I am working on a site where there is some authentication that is triggering a popup like the image below. I have deleted all the JS and CSS using firebug and it still triggers the popup. Has anyone used a popup like this and how is it being generated so I can stop it.
I can’t give out the link to the site so I know its hard for people to answer without the code but I’m hoping someone has implemented something like this popup and can put me in the right direction.
I feel like its a ghost popup right now 🙂

This is HTML5’s validation. If you specified attribute
typeasemail, HTML5 compliant browsers will validate the input as an email address.You can turn these off by including attribute
novalidatein yourformtag, like so:Reference: https://www.w3.org/TR/html5/sec-forms.html#element-attrdef-form-novalidate
