As a Firefox user, I hope this works. As someone who works in IT, people are going to try and install Chrome at all costs and your ticket queues will be clogged with people saying a computer is broken or has no internet access if it doesn't have Chrome on it.

For general-purpose use this may be true. For specialized Web-based tools, like access to medical or legal systems, not as much: the users are conditioned to work with a specific browser (many remember MSIE-only apps), and are used to the idea that their workstation has all kinds of Internet access limitations, along with a corporate policy that expressly forbids arbitrary browsing.

An earlier company I worked at had this same issue with Internet Explorer. It was after IE had been deprecated by microsoft as a browser but our IT department still had it as a downloadable application. Most of my team's on-call issues were from internal users using IE to access our site, even after we added an IE compatible popup that would tell them NOT to use IE.

Change the icon to look like Chrome?

I tried for a year to use it before just switching to Brave and getting the best of both worlds.
