Enabling extensions in Chrome on a Mac?

I already know how to enable extensions in Chrome on Windows (by adding the --enable-extensions command line parameter).

My question is how to do this on a Mac? Are Chrome extensions even supported at this point on the Mac? If so, how can I go about adding this command-line parameter, without having to launch Chrome from the Terminal every time?

Extensions are now enabled in the Chrome Developer Channel for the Mac.

Chrome extensions are not yet supported on the Mac.

So, extensions aren't supported in the Google Chrome app for Mac, but the latest Chromium build supports extensions.

You can get chromium at http://www.chromium.org/
