Hello whichonespink? - If you want to export your bookmarks from Firefox in LM16 and import them to your new LM17 installation, first get yourself a USB stick that is formatted FAT32. Plug it in, then boot up LM 16. Open Firefox, then press the key combination "Control + Shift + O" (that's capital letter O, not numeric zero). When the Bookmarks Library opens, select "Import and Backup", then click "Backup". In the new panel that appears, click "USB STICK" on the left side panel, then click "Save" on the bottom. Now you have a .json file stored on the USB stick. Close all open apps and reboot into LM17. Follow the same procedure except select "Import", then "Restore File", and again click "USB STICK" in the left side panel. Click and highlight the .json file, then go down and click "Open". That's it, all your bookmarks are copied from Firefox in LM16 to Firefox in LM17.
"Democracy and socialism have nothing in common but one word, equality. But notice the difference: while democracy seeks equality in liberty, socialism seeks equality in restraint and servitude." - Alexis de Tocqueville
