The data parameter is an ArrayBufferView, Blob, DOMString, or FormData object containing the data to be transmitted.


no plain old key-value JS object :| serialization of an object to a string up to the developer


always POST, not possible to send GET :|


when DOMString passed, the request type is Content-Type: text/plain, hence expressjs middlewares that read postdata won't process it :/ need to write custom middleware

                Installing old version of Firefox on Windows for testing and preventing it from self-updating
              
          
      View installing-old-firefox.md
  
    
Grab old version of Firefox from Mozilla's FTP. They downloads are placed in folders that follow a simple naming convention. For example v63.0 is here:

https://ftp.mozilla.org/pub/firefox/releases/63.0/win64/en-US/


Run the installer and install it to a folder like c:\software\firefox63


IMPORTANT: turn off internet connectivity at system level before running Firefox for the first time! Otherwise it will automatically self-update! (Windows 10 has "airplane mode").


Create a shortcut with special command line switches

    When sharing your screen -- during an on-site presentation, a remote meeting presentation, a conference talk -- there are a lot of small things to consider to make the experience better for the viewers. It's paramount to accommodate for the fact that your viewers will perceive things differently from youself due to where they are and their individual predispositions.
General


Make sure your pointer is visible to the users (or accommodate for it if impossible).

For example, when sharing mobile screens, people don't see where your finger is. Demos which rely on you tapping the device in places invisible to the observers are bad. Accommodate for that by telling upfront where are you going to tap.
When using tools like Vysor, prefer clicking things on your laptop with your mouse, instead of directly tapping with your finger on the device.


Make sure people in the room and the ones connected remotely *c
