I don't see it on my personal laptop on Firefox (Linux Mint), or on my workstation at work also using Firefox (Ubuntu 14 - no plugins).
Edit:
WOW I can't believe this, I opened it up in Chrome and it works / shows the comment folding option. It astounds me how much Chrome is becoming the new IE in regards to functioning websites where I wont be surprised to see (or not see) more cross-browser issues when using Firefox instead of Chrome.
Can I have the web where everyone wanted to be backward compatible with all browsers back?
Edit 2:
Also wondering how this got published by Reddit and nobody noticed some basic site functionality missing?
