Question

I’m developing a Chrome extension and I’m wondering is there a way that I can detect which version of Chrome the user is using?

Answer 1

Get major version of Chrome as an integer:

function getChromeVersion () {     
    var raw = navigator.userAgent.match(/Chrom(e|ium)\/([0-9]+)\./);

    return raw ? parseInt(raw[2], 10) : false;
}

I’ve updated the original answer, so that it does not throw an exception in other browsers, and does not use deprecated features.

You can also set minimum_chrome_version in the manifest to not let users with older versions install it.
