Keyboard keys not working properly for flash games

1. Each time I go on a new website, I constantly need to allow permission for adobe flash player to run, it's annoying. When           I go to settings, there is no option to always allow.

This is a recent change in Chrome 69, released in September.  Per Flash Roadmap - The Chromium Projects

Non-Persisted HTML5 by Default (Target: Chrome 69 - September 2018)

Summary

Sites using Flash will require explicit permission to run, every time the user restarts the browser.

Rationale

Require affirmative user choice to run Flash Player content, without that choice persisting across multiple sessions.

2. Each time I try to play a game that requires flash, the keyboard keys do not work properly. If I press a button to move a           character to the right once, the character continues moving right for some reason, This works with all the keys on           various different websites for various different games.
