hi i wanted to install a plugin...google chrome v2 support plugin now right? so i still need to do the steps below?

2. Add -enable-extensions parameter:

I. Right click the Chrome icon in your desktop, then click Properties.

II. Click Shortcut tab.

III. Add -enable-extensions parameter in the Target field:

Yes, you still need to add ' --enable-extension ' in order to use extensions.
If you try to install an extension ( .crx ) while you are not using ' --enable-extension ' , Chrome will ask you to add it.
