Anyone else notice that you can't shop oldnavy.com with firefox on Linux? What makes this really strange is that Firefox on Windows works fine. Actually if you get the User Agent Switcher to say that you're IE on windows. (or even Firefox on Windows) the site works fine. The question is why is OldNavy not wanting Linux business? While it would be easy to put on my tin foil cap and shout out Conspiracy, this time I think its just a matter of their web developers not knowing better. A quick google and I found that Safari users are having the same problems.
