If you ever needed to open Google’s web browser Chrome, without having the previous session brought back, you can actually do this from the command line.
On the MacOS, you can use the Terminal.app application to type in the following commands:
$ cd /Applications
$ ./Google\ Chrome.app/Contents/MacOS/Google\ Chrome --home
Google Chrome should start up for you without bringing up your old pages or old tabs.
Hooray for startup options!
