I'll help you get to the bottom of this issue without a moment's delay, @jagrover.
What error or message appears when you try opening your company in Firefox? To further deduce whether or not there's an issue with your browser, try loading QuickBooks Online in a FireFox private window. This can be opened from within Firefox by pressing Ctrl+Shift+P. Within this new window, head back to QBO and try opening your company again.
Should the issue persist, please be sure to make a note of the error message or whatever behavior prevents you from loading the company. Any additional information or screenshots you can provide me will help to expedite the troubleshooting. Thanks for coming to the Community, and have a very Happy New Years!

I’m having the SAME issue. It will not open in Firefox, just a blank white screen after I login. But it will open in safari no issues.

If you haven't, you can give it a try. QuickBooks will open in the Mozilla Firefox since it's one the browser that QuickBooks Online supports.
Afterward, reopen QuickBooks.
