Currently when viewing PDF files in the browser (using pdf.js) the space key doesn't do anything useful. It should be equivalent to page-down. Reproduced on http://post.queensu.ca/~khomhf/docs/msr13-Wang.pdf
With the current nightly(24.0a1 (2013-05-28)) the spacebar causes the page to scroll down like any other web page. Are you seeing a different behavior?

WFM now. Was this recently fixed or did I just have something weird going on personally?

I believe this regressed in FF22 and was fixed in FF24. https://github.com/mozilla/pdf.js/pull/3177
