people still use netscape? try backing up from netscape then import from file to TB

cmjprous: would you provide a step-by-step for "backing up" and "import/ing"? I'm using a Macintosh computer. I did try making a copy of Netscape and importing, no luck.

This should help link is a video how to https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer

this is from a mac site https://macosx.com/threads/how-to-backup-mac-thunderbird-in-the-quickest-possible-manner.323961/

Thank you for your replies. I did what you suggested, to no avail. Would have helped if I gave this info in my original question:

I want to import all settings, data, folders FROM Netscape 7.2 Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7.2) Gecko/20040804 Netscape/7.2 which is on a PowerMac G4 running OS10.11.4

TO Thunderbird 52.9.1 on a Macbook Air running OS10.12.6

Again, I need to transfer my Netscape folder "Templates" to Thunderbird, on a Macintosh. If you know how to do this, please reply. Thanks, Clay O.
