flash player

You tell us we won't miss it and to be more specific, yet your answers are vague and at times misleading like we won't miss it.  I've deleted it, as requested, only to run into a situation where I had to reinstall flash player to see something on a web site.  No I can't tell you what it was or where because I visit hundreds, if not thousands of websites every couple of weeks!  I do what I need to do or get the information I need and move on, fast! 
I don't understand why we can't keep old versions for those dummies who do not update their sites for the new way of doing things.  As you stated, "MOST software does not require Flash Player."  And yet, there must be thousands of old sites with good information that still have the old format and people are just not willing to spend the money to update them.  It should be our choice whether we want to keep it and use it or not instead of you forcing a stop on the browsers that we use. Or am I misunderstanding that?  Will we sill be able to use it with FireFox and other web browsers after the fact without support?  Thank you.

Kinda gotta websearch for a standalone swf player. https://community.adobe.com/t5/flash-player/psa-playing-flash-after-2020/td-p/11716613

But I have a lot od documents. Will I be able to open them?

#1 That's correct.

#2 You can't.

#3 That's highly unlikely.  Most software does NOT require Flash Player.

#4 No. Flash Player will not work after Dec 31st.

Stop worrying about Flash Player.  When it's gone, chances are you will never miss it.
