Google Calendar not opening in Firefox

Today, Google Calendar is not opening. I keep Google as a pinned tab set to automatically open when I start Firefox, so always available. But today it did not open. No error message, just a blank screen and the blue line moving across the top of the window. The same thing is happening when Zoom webinar registration attempts to save a calendar item to my Google calendar. No error message, just a white screen and blue line moving across the top. I am able to open Google Calendar in Chrome and also can open it in Firefox by opening a new tab and then repinning it. But if I close the browser window and the re-open it (something i have to do every day or two to keep GMail from bogging down - that is another question!) then the saved pinned tab will not reopen again and I have to go through the manual reopening process again. Any clues? Thanks!

Google reverted the changes that caused this issue on their servers, so it should be working again.

I've recently seen quite a few reports of issues with accessing Google Calendar, so it looks that something is seriously wrong. You can check the Web Console for possible error messages.

You can try to hide and show this content to see if that has effect.

There has been a bug report created where you can follow the progress.

I did not check the range of failure modes at the time I posted that. I have since tested all of them and all is indeed working properly again. Thanks!!
