This seems to be an intermittent problem that occurs occasionally with disqus. Have you tried a different browser to confirm it's not something on their end?

on the other hand, if it is a firefox issue, In another thread someone said refreshing/resetting their firefox worked in resolving the issue (it doesn't delete your bookmarks and stuff) See that thread and the chosen solutionhere.

The controls are enabled using the Tor browser. It's something with FF...

Did you check these buttons in the Inspector ?

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.

• switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
• do NOT click the "Refresh Firefox" button on the Safe Mode start window
