I believe that, of browser features released, the overwhelming majority are enabled by default (if they even can be disabled). Including TLS/https warnings, tabs, automatic page unloading, support for new HTML/JS capabilities, and so on.
Those don't generate an outcry--they're usually celebrated, in fact--so either browser updates are "usually" fine, or you have an extremely un-usual threshold for wanting things not to change.
All of those were, as far as I know, enabled by default and released in browser updates.
