Built-in Package Capture inside Chrome
This is a light weight tool built inside chrome, type
in the browser, you can find the following UI:
Now you can do whatever you can from the browser, this tool will capture all the packages, just like Wireshark.
Well I have to admit Wireshark if much more powerful for its awesome filter, but sometimes if you are really urgent and you just need a simple capture, this is a good option.
By the way, type
chrome://chrome-urls/, you can find more interesting stuff :D
