After setting up my new computer and re-installing Mozilla Firefox, I found that I no longer had my bookmarks. Any way to retrieve them?

Do you still have your old computer set-up and working? If you do, go to that computer and open up Firefox on that computer. Click 'Bookmarks' on the toolbar and select 'Organize Bookmarks'. Once the new window opens, you'll see some little icons with drop-down menus in the bookmark organizer. Click on the far right drop-down icon and select 'Backup... '. Choose a destination for your back-up bookmarks file. Once it's done, copy this file onto a flash stick or email it to yourself. Then go to your new computer, copy that back-up file to your hard drive and fire up Firefox on your new computer. Once Firefox is running, select 'File' and then select 'Import'. Once you select the backup file, Firefox will import the bookmarks for you.
