New Site Not Working on Firefox

I get this error when trying to access the site from Firefox:

But it works OK on Chrome.

Configuration:
Macbook Pro mid 2012 running Catalina
Firefox version 135.0 (64 bit)
I have Privacy Badger and uBlock Origin but I still get the error even with them disabled

For what it’s worth, it works OK for me using Firefox 135.0 (64-bit) on Linux, with both Privacy Badger and uBlock Origin enabled.

I do see the googletagmanager error in the browser console, but the site still works fine.

I don’t see the error for the <script> at eu5.dh-cdn.net

Very odd. When I try to load the site I just get the animated dots…forever.

I’m having this exact issue on Firefox for Android. It started two days ago after months of no issues.

I can’t stand using Chrome so this is a big problem in my life. Did you find a solution?

I think I cleared the cookies and stuff in Firefox and then I had to log in again. Still find it a bit flaky on FF but it’s functional

Thanks. Clearing cached files fixed it
