If you are having issues with not being able to load certain sites in Google Chrome, not using passive FTP may be the problem. Enabling and then using passive FTP in Chrome will ensure that passive FTP sites can pass through your firewall and be loaded by the browser. Enabling passive FTP requires changing Google Chrome's Internet Options, which are also shared by Internet Explorer.
Close Google Chrome by clicking the red "X" button at the top right of the screen.
Click "Start," and then click "Control Panel."
Click "Internet Options."
Click the "Advanced" tab and then scroll through "Settings."
Click the box next to "Enable Folder View for FTP Sites" so that the box is now not checked.
Check the box next to "Use Passive FTP (for firewall and DSL modem compatibility)."
Click "Apply" and then click "OK."
Relaunch Google Chrome and visit a site that makes use of passive FTP. You can now use passive FTP sites in Google Chrome.
