A few weeks ago I started having windows shut down issues ... sometimes my computer would freeze during shut-down and sometimes it would take 3 or more tries before it shut down successfully. About that same time I noticed that Mozilla Firefox was having a bunch of javascript issues ... tried Internet Explorer and the sames websites/links would work fine. Mozilla Firefox usually won't launch now, unless I first end the firefox process in the Task Manager. I am pretty clueless, but would a different version of Java or Firefox resolve my problems? I have Firefox 3.6.13 and Vista.
