I deleted Adobe Flash on their recommendation then immediately realised that it might have not been the best thing to do. However, I have not had any problems with anything since doing so, but I do use Chrome as my browser. I went to Chrome from Edge a little while ago, when ADSB Exchange up graded and would not run on my PC (Edge) but was fine on my android phone using Chrome. It is a decision I have not regretted and even though Edge has been updated to work like Chrome and now runs ADSB, I am sticking with Chrome.
