Stack Overflow and Meta Stack Overflow prompts me that "Stack Overflow works best with JavaScript enabled". But I reconfirmed that I have my JavaScript enabled by default. I am using Firefox 3.6.

Not confirmed on Firefox 3.6 on Windows. Are you sure you have no local setting enabled to turn JS off? –

Related: Which browsers are officially supported? And what else do I need? Contains input for JavaScript whitelisting (what Internet domains are actually used, etc.), cookies, etc. –

This could be caused by Google's CDN being blocked, and hence its jQuery not being available:

For some time, the JavaScript also outputted “Stack Overflow works best with JavaScript enabled” when jQuery was not loaded. In March 2011 it became more specific:
// display a warning (like the noscript warning) even if JS is enabled, but
// jQuery isn't there (google CDN blocked etc.)
// -- no jQuery is as good as no JavaScript at all for our purposes
var checkForJQuery = function (siteName) {
  if (!window.jQuery) {
     ...
     warning[removed] = siteName + " works best with jQuery enabled";
And somewhere in April 2011 this changed to:
if(!window.jQuery)
  ...
  c[removed] = a +
  " requires external JavaScript stake overflow  from another domain, which is blocked or failed to load.";

Note that the above will not work if Stack Exchange's own sstatic.net CDN is blocked, as then the above JavaScript is not even loaded. Except on Meta, where the static resources are not loaded from that domain. So, here on Meta one might get the warning, while on the other sites things fail silently if sstatic.net is blocked.

So, for future searches:

Stack Overflow works best with jQuery enabled

Stack Overflow requires external JavaScript from another domain, which is blocked or failed to load.
