Test out scratch X/2.0: scratchfoundation.github.io/scratchx/ If you want to know why did it crash read the notes below Why did it crash? On my screen it crashed because scratchX/2.0 isn't for modern browsers...... What did you causing it to crash? Pressing the button "try out scratchX" and a random extension.
