Flash Player will stop loading content from the open web in a few days. There's not really a point to keeping it around.
Both Adobe and our browser partners have done a lot of work to minimize the risk to the larger Internet from unpatched Flash clients left on the network after End Of Life through various mechanisms (e.g. click-to-play, disable-by-default, etc.), but with the majority of the population unable to use Flash content, there's not a lot of incentive for content providers to continue to pay to keep it online. The risk of keeping it is greater than the reward, and there are good moderna alternatives to most Flash-based content at this point.
At this point, we'd recommend that you uninstall Flash Player:
