Add this to your .bashrc to make a command to restart chrome without that pesky XSS auditor

chromedev.sh

# launch chromium with or without proxy
function chromium() {
    if [[ "$#" -eq 0 || "$#" -gt 2 ]]; then
        echo
        echo "Usage: chromium [port] [enable xss Auditor]"
        echo " example:"
        echo " $ chromium 8080 1 - runs Chromium listening on 8080 and XSS Auditor enabled"
        return
    fi

    # default settings
    xss_auditor=""
    port=""

    # update this to your system specific path
    chromium_path=/Applications/Chromium.app/Contents/MacOS/Chromium

    # check that proxy port isn't set to 80
    if [ "$1" -ne 80 ]; then
        port="--proxy-server=127.0.0.1:$1"
    else
        echo "Proxy port cannot be 80"
        return
    fi

    # ensure that there's 2 arguments before deciding to disable the XSS auditor
    if [ "$#" -eq 2 ]; then
        # if it's 0 or 1
        if [[ "$2" -eq 0 || "$2" -eq 1 ]]; then
            if [ "$2" -eq 0 ]; then
                xss_auditor="--disable-xss-auditor"
            fi
        else
            # bad value otherwise
            echo "Enable/Disable XSS Auditor argument must be 0 or 1"
            return
        fi
    fi

    echo "[+] running $chromium_path $port $xss_auditor"

    # start Chromium
    bash -c "nohup sh -c '$chromium_path $port $xss_auditor' > /dev/null &"
}
