I have installed and am running Thunderbird on my new laptop, and would like to use the profile from my old computer. I have followed the instructions provided, and copied the profile (renamed) into the folder on the new laptop. When I run "thunderbird.exe-p" I receive a message "cannot find Thunderbird.exe-p" and asked to try again, but without success. I would be grateful for help on this problem. With thanks Alan

I created a shortcut icon for Thunderbird program and put it on my desktop Then I changed the Properties

  • Right click on shortcut icon and select 'Properties'
  • select 'Shortcut' tab
  • set the 'Target': "C:\Program Files\Mozilla Thunderbird\thunderbird.exe" -P

Note: if you have Windows 64 bit, then Target needs to be:

Sadly does not work - nothing happens!

Given your apparent level of technical skill, install this add-on https://addons.mozilla.org/en-US/thunderbird/addon/profileswitcher/ and use the menu entries it creates.

Note you will need to install the add-on in each profile to use the menu option it creates.

Hi Matt Thanks for your kind response. Sadly my technical skill is not that good, and I got nowhere! Rgards Alan

try these instructions to install the add-on, or any add-on. https://support.mozilla.org/en-US/kb/installing-addon-thunderbird

Hi Matt Thanks for your kind reply. No success unfortunately - I am probably too thick to succeed! Have followed instructions, but nothing seems to work! Regards Alan

Hi Alan re :Sadly does not work - nothing happens!

Have you closed /exited Thunderbird ? Thunderbird must not be running.

Thanks - sadly made no difference!
