User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:95.0) Gecko/20100101 Firefox/95.0

Steps to reproduce:

https://business.apple.com/ is Apple Business Manager, Apple's web console for businesses to manage MacOS and iOS devices deployed with Device Management installed. The website will not provide a login interface in Firefox, advising only Safari (MacOS), Chrome and Edge (Windows only) are supported.

Actual results:

Spoofing the UA string allows full functionality in Firefox on Windows 10. I have not run into one UI glitch in months of almost daily use. I have not tested this on other platforms.

Expected results:

Given the importance of business.apple.com to businesses deploying Apple devices, I am requesting Mozilla consider adding business.apple.com to the list of User Agent Overrides in about:compat. Given the very limited number of exceptions added to this list (the most recent of which was Slack in Bug 1727100) I appreciate this may not be considered a priority or may be turned down for other reasons, but I feel it doesn't hurt to ask!

[BugBot [:suhaib / :marco/ :calixte]]

The Bugbug bot thinks this bug should belong to the 'Core::Graphics: WebRender' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

I re-pinged Apple about this, but it's probably also a good idea to see how they detect Firefox and if there is a non-risky way for us to spoof.

ni? myself for investigating.

Would appear to also apply to https://school.apple.com/

I'm the OP. Unfortunately business.apple.com is no longer fully functional in Firefox when spoofing the UA string. Specifically, the selectors when filtering in Devices no longer work when pressed.
