Our policy, since most folks work from home a significant % of the time, is to allow employees to use whatever Office Suite, browser, etc they prefer whether here or at home. We provide and support the PCs at both. Only hard exception is AutoCAD as sharing files is tedious and worrisome. Only restrictions we have ever had were client initiated as when we were doing work for a certain federal agencies, we were not permitted to use MS Office; this was back in the day of the "concept" viruses and I guess someone circulated a memo I guess stating that this could lead to the fall of civilization as we know it. But we don't tell clients what to do, I have learned that if ya don't do what your clients and wife want, then you don't get what you want. And I know what you're thinking ... But I am referring to repeat business (client) and peace and quiet (Wife),
Our problem was, with identical machines with identical OS installs and identical software, one machine would work just fine with Chrome and the other was totally boinky. Spent hours and hours trying to figure out WTH and finally just gave up. Removing Chrome solved the problem. I still don't know what problem is other than i don't have to deal with it anymore. As for Chrome versus Edge on data mining ... two sides of the same coin.
On the personal side, I find FF the most functional and having the most choices .... privacy options improve with each release. As it's open source it's to be exected that users feel safer using it, from a privacy perspective, than other closed alternatives since anyone can examine it. As for the "infection stuff" in over 230 machine-years (No, of machines in use x Years of each use), we have never "had" an infection. In that time, have had about a dozen false positives, most of those associated while converting spreadsheet based tools to In Game Applets for Saga of Ryzom Game. I handle the math side, buddy does the WebIG programming and it was some Delphi DB thing that some vendors AV tends to trip over. In each case it was submitted to vendor and determined to be a FP. With a) a good hardware firewall, b) a good subscription based AV / Malware Suite and c) sound user practices, you should have little to fear from infections... that being said, I think given the choices availabe, it still makes perfect sense to avoid anything with a history of vulnerbilities
