I have said this here for years and now it is more true than ever.
For one thing, Chrome does a painless (if at times less than perfect) job of keeping the Flash Player up to date with bug fixes.
It is packaged one way for use with Internet Explorer (an Active X control) and another way (referred to as the plugin version) for use with Firefox and Opera.
Adobe used to have a fourth Flash tester but sometime in Jan 2014 or earlier, it was merged into the above. 2014) FLASH PLAYER on CHROME OS (created Oct 15, 2015) I ran into an interesting wrinkle while logged on as a Guest user on a Chromebook.
The upside to being a guest user is that you always start with a virgin copy of the operating system.
Many times the Chrome browser has reported that it was up to date, yet Flash was not.
GOODBYE FLASH This site (page really) started as way for me to easily find the main Adobe Flash tester page (links at the top above) which reports both on the installed copy of Flash in your browser and the latest version for assorted operating systems.
The end user is not told or asked, which, in my opinion, is the way it should be.
In addition, Chrome does a better job of sandboxing Flash than either Internet Explorer or Firefox.Each Windows browser self-updates Flash using a different mechanism.Internet Explorer, in its never-ending quest to be the worst option, updates Flash one way on Windows 7 and a different way on Windows 8.x.At one point, I was viewing a single web page and the Chromebook was sluggish.I used Shift-Escape to bring up the Google Chrome Task Manager and saw that the Flash plugin was using a lot of ram and CPU cycles.If your browser tries to download a file, Flash is not installed. But current browsers download the file rather than displaying it as a web page.
