In the past month , QuickBooks Online has begun hanging while I'm using it in Firefox. It seems to happen mainly when I open an item from a list, like a vendor bill or a customer invoice. I can't click through to expand the item or see the details from a report. When I refresh the page, I get to the page I want to be, but then I have to re-navigate back to the list.

My Windows OS is fully updated, I'm using the most updated version of FireFox, and my high-speed internet is working just fine. I don't have a large number of tabs open in FireFox or a large number of other internet-based programs open on my machine.
