Verticle scroll bar disappears except when at extreme wide window
I've recently noticed that when I use a less than full-screen-wide window, my vertical scroll bar disappears.
As far as I know, I have not added any new plug-ins or patches for Firefox.
I am using 3.6.1

Window sizes and positions are stored in localstore.rdf in the Profile Folder.
Delete localstore.rdf or rename the file to localstore.rdf.sav in the Profile Folder to test if the file is corrupted.
See http://kb.mozillazine.org/Corrupt_localstore.rdf
(caution: do not delete the localstore.rdf file in the Firefox program installation folder)
Note:
Deleting the file localstore.rdf will reset the customizations of the toolbars to the defaults.
You can rename "localstore.rdf" to "localstore.rdf.sav" to test if that solves it.
Then you can restore the customization by copying "localstore.rdf.sav" to "localstore.rdf" if it didn't work.
You can also try to move (delete) the Firefox plist file.
See How .plist files become corrupt and troubleshooting the results
Go to "Library > Preferences" and remove the plist file for Firefox (org.mozilla.firefox.plist).
