Firefox shows [object Object] on pages with code blocks

more options

Since a couple of months I see only [object Object] instead of code blocks on (almost) all web pages. For example on StackOverflow.

Any ideas what could cause this?

The problem was caused by the Merlin extension. Disabling the extension fixed the issue.

[object Object] sounds like the return value when you haven't called the right property or function on a JavaScript object.

I don't know what is causing on that post -- it looks normal to me: https://stackoverflow.com/a/3723649

Could you try temporarily disabling any extensions you've installed during 2023 and see whether that makes any difference?

Any difference when you test in Firefox's Troubleshoot Mode? See: Diagnose Firefox issues using Troubleshoot Mode (do not "Refresh", just "Open").
