Little confused about removing Adobe flash


I had a popup to remove Adobe Flash about a month or 2 ago, but I hadn’t heard anything about it at the time so just closed it until I could investigate. I’ve been waiting for it to popup again, but it hasn’t and its getting close to the end. I know how to manually delete apps through Windows, but I have to also remove them from my browsers and other programs from what I saw in my searches.

I don’t know that will be accomplished merely by removing it from Windows “Apps & features”. I found that when I use the app remover there are always still remnants of them left behind especially with Antivirus programs. So should I remove them 1st from Chrome and Firefox then from Windows?
