* Add paragraph about browser add-ons when encountering some errors When a crash is caused by a NotFoundError exception, add a paragraph to the error page mentioning browser add-ons. Indeed, crashes with NotFoundError are often caused by browser extensions messing with the DOM in ways React.JS can't recover from (e.g. issues #13325 and #14731). * Reword error messages
