I was able to find the required .plist file to use this utility, but when i drag it into the "drop zone" I am prompted with this message:

"oops, import failed

The file you tried to import was not in the correct format."

I haven't done anything that would alter the format, so why isn't it working?

Thanks!

@SweetP wondering if you've figured out where the sessions are stored post Mojave? I'm in the same predicament as Arlo - can't find my backed up plist files to extract sessions from.

I tried your suggestion of .../safari/extensions.plist and that didn't work for me.

any updates?

I installed the extension in Safari, but it does not work. I hit the "save" button and it does nothing. I go to the "save current safari session" under the file menu and it does nothing.
