I am using Firefox 4.0 Beta 2 on Vista Ultimate and the browser.tabs.tabMinWidth doesn't seem to work (have set it to 150). I've restarted the browser since setting this configuration, but that hasn't had any effect.

Has this setting been deprecated/removed in Firefox 4.0?

Firefox was started with command: firefox.exe -no-remote -P FF-4.0-B2

Yes, those prefs no longer work.
You need to use CSS code in userChrome.css to accomplish that. 

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */

.tabbrowser-tab:not([pinned]) {max-width:250px!important; min-width:100px!important;}
.tabbrowser-tab:not([fadein]) {max-width:1px!important; min-width:1px!important;}


Add code to userChrome.css below the @namespace line.
