I haven't been able to reproduce this myself on OS X, where it seems to work — so if someone knows that it isn't a problem on Windows/Linux either, feel free to close this:

When you load a really long page, I got a report that the scroll bar becomes so small as to be unusuable, ie. just a couple of pixels. There should be a threshold value here so it never becomes smaller than a reasonable size to manipulate.
Depends on: 502292
I loaded this page and the scroll bar thumb stayed large enough.  
http://dev.w3.org/html5/spec/Overview.html

The scroll bar thumb is larger than what you get in IE7 on that page.

This is using this build:
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.3a5pre) Gecko/20100514 Minefield/3.7a5pre ID:20100514040039
Using the Zune theme.

The thumb in 3.6 is smaller.  I wouldn't call it unusable.  But something must have changed on the trunk which looks like bug 502292 as mardeg pointed out.
On Linux, I have seen the thumb getting "too small". Not as in "unuable", but "visually unpleasing". IIRC this was more of a problem in lists like the one in the Page Info (media) window
On Linux/windows, I have been going crazy with the thumb getting "too small" as in "unusable"

FWIW, I see this bug every day in Thunderbird where some of my folders have many
thousands of mails.
So here's what the problem looks like in Thunderbird when you have a folder
with thousands of emails (the www-style mailing list).

It appears as if only the top part of the thumb is taken into account
for its height, i.e. that part where the rounded corner starts.
I suspect it might be a nscoord overflow error in Layout (nsSliderFrame.cpp?)
