click tools>import>import from a file and then follow the menus for addressbook and select the sqlite option and then locate and select the abook.sqlite file from old profile. Repeat the process for the history.sqlite file. AND, if you're comfortable with windows file explorer, just exit thunderbird, and copy the abook.sqlite and history.sqlite files from old profile and paste into new profile and restart thunderbird.

i just tryed and cant find old profile. then tryed to import address book and got an error msg thanks

i got far as a window called "select an addres book file" but dont know where to look for it.

i then tryed ti import it another way but got an error,

If you can start thunderbird on old PC, do this: - click help>troubleshootinginformation - scroll down to 'profile folder' and click 'open folder' - exit thunderbird - you are now in the profile. note the exact location on the disc. you are in the folder with abook.sqlite and history.sqlite. copy both to external media and you can then follow previous steps to import to your new pc.

ok i'll; try that and be back here in cpouple of hours...thjanks

hi ive done that now but only managed to import 10 addresses, there are more like 100 on the other pc which should be coppied successfully

also what should i do with "history" file i copied
