Google workspace threatening to block firefox

At the time of writing (2026-06-18), Google Workspace appears to be starting to warn users from Firefox that they must use Chrome. This was for a Google Workspace Business Plus account and workspace, from an up to date browser and OS.

At this time, Firefox access still seems to work but I’ve no idea for how long.

Specific warning

Response from Google support

Absolutely nothing useful, repeatedly transferred around and took ages.

Why do I care?

My team need to make sure that their software works in multiple browsers, and I personally prefer using firefox and don’t want to be forced to use Chrome for no discernable benefit.
