Your screwed here. I have tried chrome, firefox, and edge. all 64bit. there is a problem with a webpage going out of control and chewing everything up. chrome gracefully asks you ro killthe page. all browsers leak memory, handles, etc. pisspoor programming poor standards adherance etc. hell your eseentially interpreting everything anyway. just don't run gunbot in browser more that you have to.
most every exchange will shutdown the browser every so often.... just facts of life.
