DatePicker in the List in Firefox stopped working

[Leon Kuper]

Sharepoint (Office 365)

The DatePicker in the Sharepoint List stopped working recently in Firefox only (a Calendar drop-down doesn't pop up). It works in Chrome.

I can't figure out what could cause this problem. Installed older Firefox versions but it still doesn't work.

Has Microsoft changed anything in this regard? Javascript issues?

In the Web Console I see this:

The supported browser statement is a bit vague, to me it suggests that support for Firefox is not universal. If you have the very latest version of Firefox installed and you are seeing the same issue across multiple computers then best bet is to raise a ticket in the Microsoft 365 admin centre and get an answer off support. I would bet the solution is to use Chrome. 

Statement is here - https://www.microsoft.com/en-US/microsoft-365/microsoft-365-and-office-resources?CorrelationId=8964a...

The phrase is "Most" apps but not supporting Teams tells me Firefox is on the way out of supported browsers.

@Andrew Hodges,

"...then best bet is to raise a ticket in the Microsoft 365 admin centre and get an answer off support..."

Good luck with that ... Yoga class and some meditation are more helpful.

I believe that this is just a web browser war.
