I am noticing this attribute added to HTML source, I can't find any information about it.
It starts in the head tag:
<html wtx-context="8F1EE800-7352-408E-AC70-5297G5FD3F25">
It also appears in form elements and inputs.
Any information would be useful, such it's purpose and what it is thats inserting it and why?
Sorry, late answer. I browsed the web for this question too but didn't find anything useful. It happens that I installed bitdefender a couple of days ago and guess what ? It's the culprit. Even if its extension is disabled, it adds this weird attribute. I completely uninstalled the plugin (not the AV) from my browser (chrome) and that's it.
