Hi,

You can try to change the Home Page: in Tools (Alt + T) > Options > General. Options > General

For the bookmarks please try restoring a backup via Bookmarks (Alt + B) > Show All Bookmarks (or Ctrl + Shift + B), click Import and Backup on the top left > Restore. Restoring from Automatic Backups

If the menu bar is hidden then press the F10 key or hold down the Alt key to make the menu bar appear.

Make sure that toolbars like the "Navigation Toolbar" and the "Bookmarks Toolbar" are visible: "View > Toolbars"

• Open the Customize window via "View > Toolbars > Customize"

• Check that the "Bookmarks Toolbar items" is on the Bookmarks Toolbar
• If the "Bookmarks Toolbar items" is not on the Bookmarks Toolbar then drag it back from the toolbar palette in the customize window to the Bookmarks Toolbar

• If missing items are in the toolbar palette then drag them back from the Customize window on the toolbar
• If you do not see an item on a toolbar and in the toolbar palette then click the "Restore Default Set" button to restore the default toolbar set up
