Just occurred to me there might be someone here who has a clue as to why I can't get into the IRD site in Firefox? I'm an accountant so go in regularly - but started having problems a couple of months ago - waited till 31 March was over. I can get in via Chrome - added it to my taskbar.
Even when Chrome was faster I saw no reason to change, and don't want to change now. My Chrome has very little customisation - I use it on the odd occasion to check when I have problems in FF (seldom except with IRD).
I've tried FF safe mode, normal mode with add-ins disabled, pop-ups disabled (wouldn't expect IRD to use them), etc. Nothing works.
So if anyone has any ideas ... IRD say to get my IT section on it - this is as close as it comes to "an IT section" at our home office.
This is the error when trying to get the login screen:
The request could not be understood by server due to malformed syntax.
