When I start firefox, the reload current page button, the stop loading page button, the Web of Trust button, and the forward and backward buttons are grayed out. To go back, I can right click either the forward or back button. Now if I go to firefox help, and then go to the Firefox Web site and click on the SEARCH icon on the page, the buttons return to their normal color. Every thing seems to be normal. The other hyperlinks seem to work the same way. Also there seems to be a problem with the bookmarks
