I tried Brave. It seemed faster than Chrome. But I encountered web sites that didn't work and I didn't like all the nagging from Uphold. When I went to uninstall, I found that its updater didn't uninstall at all and it was hard to eliminate it. Needed safe mode in windows. My advice is not to install Brave. I'm back to Firefox, which seems much better than 2 years ago.

MIT's open courseware, in economics, is underwhelming. There is much more material available elsewhere and most professors have at least as extensive sites. I think this is mostly MIT grabbing publicity for content ordinarily available online.
