Why does adobe flash player want to download on every website I try to go to?

Question

After signingin to my website, and trying to go to another thru a visual tag, I get a message from adobe to doenload the flash player. Isn't once enough?? Can't the programmers send a tag to see if it has already downloaded the flash player??
I'm just an old fart, but they should get their heads out of the sand and put a tag into the add on tag to see if the flash player has already been downloaded. If so, continue with the site downlosd.
This crap just makes it harder to access websites.

That would be 11.

But the problem is more likely IE11 itself. Aside from Vista, it's just about the worst garbage Microsoft has unleashed on the computing public, ever. They intentionally altered the "User-Agent Strings", which websites use to identify the browser and provide the proper content for it. Some sites ID it as a Gecko browser (Firefox), while others ID it as a Webkit browser (Opera or Safari). Problem is... when the site ID's it as either of those, the browser specific content supplied REQUIRES the correct browser engine... which IE doesn't have and never will. So, it then becomes an "unrecognized browser". The pages can't recognize the browser, so they don't recognize any of the plugins, like Flash Player. So far, Microsoft has made NO indication that they have any plan to fix it soon. In fact, since they though this was a great idea, I seriously doubt they'll change it at all.
Microsoft's recommendation is to use Compatibility View for affected pages, and "pretend" you're using a different browser. Trouble with that is... it's seen limited success at best, and you have to individually enable it for EVERY page that has problems.
I'm not big on "pretending" so I recommend actually using another browser.
Firefox (from Mozilla)
Opera (from Opera)
Safari (from Apple)
Chrome (from Google)
ANY of those will work where IE11 won't, with the Flash Player Plug-in (For all other browsers), and Chrome doesn't even need that because it has its own Flash Player plugin built in.
