This beta 5 is far better than the previous one when you use the Firefox + Eset combo, however there are still some problems. There are some instabilities from time to time, when the Firefox window takes up to a minute to react to the close/minimize/maximize buttons. There are also -some- files that are downloaded corrupted or empty if DisplayFusion is active (mods from the Nexus, updates for YoloMouse...). If DF is off or if I use another browser (edit: same problem with Brave), no problem with the same downloads. That download problem was already present with the previous beta.
