I'm using the exbrowser plugin with Firefox Portable version. When I login to the site I get a captcha and two-factor authentication. I've authenticated it manually and ticked the box 'Don't ask for codes on this device' but each time it launches a new instance of the browser I have the same problem. Is there a workaround for this? Can I save credentials into Portable Firefox somewhere or something? I can't get my head round how to solve this and I'm hoping it's a simple fix.
