With the future of the open web and privacy at stake, it's imperative that we stop letting the IT department or some random web service from dictating our choice of web browsers based on their convenience. If something doesn't work on Firefox, we should be collectively putting pressure on those in charge, letting them know that their laziness and lame excuses amount to forcing us to install spyware on our system.

You can report websites that don’t work in Firefox on webcompat.com and Mozilla web developers will test and diagnose the problem. When possible, they attempt to reach web developers at the site (using personal contacts or referrals when official channels aren’t working) to share the bug report and a suggested fix. In other cases, Firefox can include a site intervention script to patch the site or send a different browser User-Agent string to make it work.

Use chrome for work and ff for everything else. You should keep your work and personal stuff separate anyway.

There are at least two other ways to keep these things separate while only using Firefox: containers and profiles.
