I'm trying to upload multiple photos onto facebook but a message keeps appearing saying I need to update my flash player which I have done several times as well as enabled (disable/enabled cycle). I've also done several other things and the same message keeps showing. Computer has been turned on and off several times too. I don't want to use the simple uploader as I don't have the time or patience for that.
This is a known problem with Internet Explorer 11, which Microsoft has been aware of since October 18 when they released their latest "untested" 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.
Microsoft's recommendation is to use Compatibility View for affected pages, and "pretend" you're using an different browser. Trouble with that is it has 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.
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.
