If I remember correctly, the issue was they were moving to sandboxing and NPAPI plugins had a lot of issues with security at the time. There was a new flash vulnerability almost every week, and usually it meant getting a lot of control over the browser.
i kind of miss it, because there was an tribute game called aot tribute game it was very fun, i used to play it alot back in 2015, and i remember it only ran on firefox after chrome booted out NPAPI
