This nemo action script adds an "Email with Thunderbird" item to the context menu in the nemo file manager.
To install, copy the email_with_thunderbird.nemo_action and email_with_thunderbird.py to the ~\.local/share/nemo/actions folder on your computer.
You can customize both the binary location and your thunderbird profile location. To get started, navigate to your home directory, adjust display settings to show hidden files, and then open the .config folder. In the .config folder, create a new folder named nemo-email-with-thunderbird. Open the nemo-email-with-thunderbird folder. To customize the thunderbird binary path, create a file named thunderbird_path.txt and enter the binary as the only line in the text file. Similarly, you can customize the thunderbird profile path by creating a file named profile.txt and entering the profile there.
