The problem is proprietary systems that are mandatory to interface with. I have chrome installed for these stupid bullshit situations and as a result it’s constantly so far out of date that I just end up having to reinstall it the once or twice a year I am forced to use it.

Government interfaces are the one I run into the most. I recently had to log into nppes, the us government database for updating information attached to the national provider identifier number for healthcare practitioners. Super important thing, literally necessary to bill every single insurance in America and to join basically any practice. Locked out of the site unless you use edge or chrome. Like scripting on the page that makes the page blanked out for any other browser (including older versions)

Similarly I just had to pay the local tax bill in my county and their website had the same deal although they also supported safari. The website is blocked out with Firefox and brave. Could get past that but the website still didn’t work right even trying all 3 of their “supported browsers” on 2 different computers and a vm. lmao except I still have to figure out how to pay my taxes
