I cannot reproduce the issue on my Macbook. Oana, is it still reproducing for you on the latest nightly Firefox build? If so do you see any errors in the console as you click? I do see two of them, one where "ire" is undefined, and one where "fbq" is undefined, but neither seems to break my ability to navigate between categories.

Tom, the issue is still reproducible after selecting the second category. I've attached the console log.

Tested with:
Browser / Version: Firefox Nightly 96.0a1 (2021-11-24)
Operating System: macOS Big Sur 11.6

Tom, please check the provided attachment that shows the console log.

Ah, good, thanks! I was able to reproduce the error today, and it helped to see what you were seeing!

It turns out that this site is relying on an early Google Analytics command-queue which we're not handling properly in the SmartBlock shim, so it's missing the tracker object which should be set as ga.getAll()[0].

Thankfully this is simple enough to fix; I have a candidate patch almost ready.
