There are two different methods, so this message is a little long even though the procedure is not difficult. Does your old computer still run? If so: '''On your old computer''', go to Help > Troubleshooting Information. In the "Application Basics" section near the top of the page, you should see a button labeled "Show Folder" or "Open Containing Folder". Click that, and Windows should open your active Firefox settings folder. Do you see a folder in there named bookmarkbackups? If so, great, open it up and drag and drop the files there to USB flash drive (or other shared storage such as a Dropbox folder). If not, you can export your bookmarks to an HTML file directly to your shared storage device/location. This article has more information on how to do that: [[Exporting bookmarks to an HTML file]]. '''On your new computer''', you can restore your backup or import your HTML file. Since the procedures are different, here are articles covering each method: [[Backing up and restoring bookmarks]]<br> ''Please Note:'' restoring the backup will replace/wipeout/overwrite any bookmarks you added on your new computer. Probably not an issue in this case. [[Importing Bookmarks from an HTML File]]<br> ''Please Note:'' the imported bookmarks may be added in a folder; to move them to the top level, use the bookmarks organizer (library dialog) which you can open using Bookmarks > Show All Bookmarks or Ctrl+Shift+b. Any luck? If your old computer isn't running any more but you have a backup, or if you have attached your old computer's hard drive as an external drive, locating your bookmarkbackups folder can be a bit more challenging. Please post back about that if necessary.
