Hi, One way would be to attach/connect the hard disk of the old PC to the new PC. The dedicated hardware forums would also be helpful in this regard: http://www.tomshardware.com/forum/ http://forums.cnet.com/pc-hardware-forum/ Once done, you can then copy/overwrite the '''places.sqlite''' file from the old hard drive's [http://kb.mozillazine.org/Profile_folder Firefox Profile Folder hierarchy] into your current profile. The places.sqlite stores both the bookmarks and history. You can open your current profile folder from inside Firefox: '''Help''' ('''Alt''' + '''H''') > '''Troubleshooting Information''' > '''Show Folder''', and exit Firefox before copying/overwriting. There are also a number of other files you may want to copy. Please see [https://support.mozilla.org/en-US/kb/Recovering%20important%20data%20from%20an%20old%20profile?s=profile&r=1&e=sph&as=s this].
