I normally use Firefox, and the site comes up, and I can fill in the form, save it etc. But....when the time came to hit the "submit" button, no joy. Signed out and back in just for fun. (It was a rainy day, so why not waste the time?)
Went back to Internet Explorer, signed in, retrieved the form, and surprise, surprise, the "submit" button worked. Got the acknowledgement email a few minutes later, so I assume the form is where it is supposed to be.
I had already printed a copy of the FBAR form, and did note that the on-line version is outdated. I took the precaution (?) of emailing (using the secure email on the site) and queried this. The forms do look the same, aside from the 'version' bit at the top. I got an immediate reply assuring me that the on-line version was acceptable for filing.
As an aside, wish I was as computer illiterate as theOAP......
And generally, although I used Airsure for my federal return, I think ordinary mail is often faster and just as likely to arrive at the intended destination, and delivery is typically faster. I sent my VA state tax return by regular mail this year for that very reason.
