I noticed in the last couple of weeks, when I'm using Firefox (11.0) with the latest Java plug-in update (1.6.0.31) the Add to Cart and View Cart buttons no longer trigger the pop-up cart window.
If I right-click on the button and open in new tab, the cart does appear in a new tab. If I access the same pages in Safari, everything works as it should.
Any ideas what's causing this new issue and how to resolve it?
Thanks!
