"If you have JavaScript enabled, a small browser window should have opened. If you do not have a JavaScript-enabled browser, or do not wish to use JavaScript, click here."
I don't know if I have a JavaScript-enabled browser or not.
HELP!
Well, when you go to the tool, does a window popup?
Your JavaScript has probably been disabled, wisely, for reasons of security (by its very nature, running just anybody's program is dangerous.) I recommend turning on JavaScript, et al., ONLY when you trust the CONTENT of the website, otherwise leave it off at all times.
Fortunately, you don't need JavaScript to use the FreeRepublic pager. The pager uses JavaScript only to popup an initial window when invoked in "detach" mode, which is the URL commonly given here on the forum (you can tell it is a detach URL because it ends with detach=1.) The pager functions perfectly fine without JavaScript, just open this link in a new window (same as the the "click here" from the javaScript page.)
Of course, you can then manually shrink and move that window, but why do that when you can be lazy? :)
