[ddavison]

hold off merging until I test this thoroughly. I will merge it in once i'm done.

@ddavison if your comfortable doing merges on this repo, then would you mind taking a look at #251 which does something similar for the Selenium server component and Firefox?

[ddavison]

sure thing, @davehunt

Is this waiting for tests? We would need this feature because we need to use some older versions of Chrome.

I don't how this can work for installing old versions of chrome, right now we are on Chrome 56 (stable) and if I try to install Chrome 53 the package is not listed anymore:

E: Version '53.0.2785.101-1' for 'google-chrome-stable' was not found

What am I missing?
