UPS package tracking no longer working in TFF

I noticed yesterday that the UPS package tracking page no longer works in TFF FPR14 for G4 7450 on a Mac running Leopard. I'm visiting this type of URL with a tracking number inserted at the end of the string:

This lands me on the tracking page with a spinning progress wheel, but I never get a result. TFF remains responsive, but the wheel just keeps spinning. I tried disabling TFF's basic adblock yesterday and this morning I backed off to FPR10 and also tried using various user agents, all with no change in behavior. I assume UPS changed something on their end. I have no add-ons enabled. My alternative for now is to use Leopard WebKit for UPS package tracking.

    I can comfirm the problem, also that it works on LWK. It's another instance of issue 533 ('TypeError: this is undefined'), see

    Thanks for confirming the issue, Chris. Issue 533 strikes again. I'm a Citi customer, so I'm already familiar with it, but didn't assume immediately that the UPS tracking issue was related.

    @rardin - is the missing menu on also related ?

    Yes, but the Citi issue may have been resolved by a change on the Citi end. I'd be interested to hear another Citi customer confirm that I'm not imagining this.

    Yes, they're the same underlying issue.
