IE10, IE11, Edge - all bad options, sorry to say. Quesiton is whether there are any better options left. Browsers once known to protect porivacy, old Opera, old Firefox, do not do that anymore, and instead went all to the Chrome engine, which does not relaly understand what "orivacy" means.
But its 1.247 milliseconds faster in loading a site, so the change is really justified.
And then there is Windows 7, 8 and 10 updates. All of them have messed up Explorer/Edge repeatedly over the past two years.
