Can you even do it with Firefox any more?

[skykooler]

Yes, you can do so through the about:debugging page.

But you can do the same for Chrome in Developer Mode. What's the difference?

Unsigned extensions only work on Firefox Nightly and Developer, not Stable or Beta, regardless of what you set in about:config.
