Got fed up with IE8 and switched back to Firefox. 1) Still having a lot of problems with pop-ups on certain websites (NY Post, Wash Times), even though the "enable pop-up blocker" box is checked in system tools. Do I need to add a separate (non-FF) pop-up blocker? 2) I use full-screen mode, which means the bookmarks open up on the left. Every now and then, it won't let me close the bookmarks when I click on the little x. Thus far, the only way to close them is to exit FF entirely and then start up again. Not a big deal, but annoying. Anyone know how I can get around this, or why the "x" suddenly becomes disabled?
