Anyone affected by Google Chrome stopping .dev URLs from working: as a quick fix do this

Create an overwriting google-chrome executable at:

    sudo nano /usr/local/bin/google-chrome


Make the content this:

    #!/bin/bash
    /usr/bin/google-chrome --ignore-certificate-errors

(The "/usr/bin/google-chrome" part may be different depending on your machine. Use "whereis google-chrome" to confirm it)

Then make it executable

    sudo chmod 777 /usr/local/bin/google-chrome


Then you can pretty much just write "google-chrome" in the command window and you're away (some people can also do it with Alt+F2 for quicklaunch)
