Autofill pop up don't work; Autofill extension pop up work

Hey @infinitum,

I've done some testing on the website you've provided using Firefox and have been able to recreate the same behaviour. There is a known issue with autofill on this specific website using Firefox only, I've gone ahead and added you as an affected user to our internal report for further investigation.

In the meantime, as you have been I suggested filling your credentials by clicking 'Autofill' on the extension pop up.

I'm sorry for the disruption, let us know if there's anything else we can help with in the meantime.
