After install of new 1.8.3 daily build, after setup, when viewing home page of moodle, styles are not linked. page is displayed with no style in firefox only on both mac os x and on windows firefox. page correctly shows on mac/Safari and windows/ exploer 7.
When I replaced the moodle files from the 1.8.3 stable build, styles work fine.
NOTE: in firefox, if you do a edit css with Web Developer 1.1 4, the browser then picks up the link to the style sheet correctly.
