Home > Troubleshooting Problems with Checkout for Multiple Items
Shoppers using EZ Firewall with the default settings have reported to merchants and to Yahoo! the inability to add multiple items to the shopping cart. After researching the issue with Computer Associates (makers of EZ Firewall), a problem with EZ Firewall has been identified. Yahoo! Store uses cookies as part of the shopping cart to track which items a shopper has placed in their cart. EZ Firewall incorrectly identifies the cookie set when a buyer attempts to add a second item as a "3rd party cookie" and thus blocks the cookie resulting in shoppers being unable to place a second item in their shopping cart.
This problem is further complicated by the fact that shoppers may not be aware that they are running such software that has this effect. For example, Road Runner, an ISP of Time Warner Cable, includes EZ Armor™ (which includes EZ Antivirus and EZ Firewall) as part of its service. During installation EZ Firewall asks users if they would like to enable privacy control to block popup ads, banner ads and third-party cookies.
When privacy control is enabled, EZ Firewall blocks tracking cookies; the Cookie Control setting is set to "Medium" when the user opts to enable privacy control.
To resolve cookie problems in EZ Firewall:
- Launch EZ Firewall.
- Go to the Privacy section.
- Set Cookie Control to "Off" by clicking the slider and dragging to the Off position.
You should now be able to place multiple items in the shopping cart. For more information about cookie settings in EZ Firewall, go to the my-eTrust Knowledge Base and search for "cookie control".
Other firewall/privacy software may cause the same issue:
Zone Alarm (Zone Lab)
Personal Firewall (Sygate)
BlackIce Defender (Internet Security Systems)
