Having trouble with site navigation tools on Firefox

Hi. Sometime in the last several weeks, I’ve lost the ability to navigate within a thread using the buttons at the bottom of the page (including the “Next” button). Similarly, the “New Topics” button at the top of Forum is not working for me on my Firefox (v 53.0.2) browser. Things seem to work the way I’d expect on Safari (I’m running os x 10.12.4 with the current version of Safari).

Interestingly, the arrows at the top of the thread page do work, but the “Filter” button does not.

Any idea what could be going on?

Thanks.

Sorry for the trouble.

Have you tried clearing that browser’s cookies/cache for the site?

Here’s an example of a tutorial to explain how.

Let me know if that helps!
Thanks,
