I have a Macbook Pro, I haven't used flash player since I got it in 2013 but I have this banking feature I want to use for online shopping but it requires Flash player. So what would be the most secure option for using it? I have Safari Browser and I prefer to keep my system as simple and clutter free as possible. Will installing Flash mean that it will be running all the time in the background or have other clutter involved beyond just the times when I use it? I don't want to install Chrome just because it always has a couple of files running in the background and I don't need anymore telemetry collecting my data than I have to. I was hoping to find a portable OSX browser that has Flash player built in...does such exist?
