I think you are confused, or aren't reading as carefully as I am. Please scroll up and review this thread in its entirety before further embarrassing yourself.
#1) jhfrontz started a thread titled "Is there a replacement for Lazarus (form recovery extension for Safari)?"
#2) I replied to his question appropriately.
#3) You then came along, 10 months later, and posted, "I already knew that, and that doesn't answer my question, I'm looking for a way to download the file, and the alternative you posted isn't good enough."
This was your first reply to the thread. You hadn't asked any earlier question. You were hijacking someone else's thread.
Unless you, 1AI, are jhfrontz, your replies and request here are making very little sense. (And even if you are the same person, and failed to mention this, your replies aren't make sense, AND you're being impolite.)
I'll conclude with these points:
#1) I do have the Lazarus Form Recovery extension. It no longer works and hasn't worked for a very long time. You won't be able to make it work, unless you're stll using OS X 10.8. It broke with 10.9 (Mavericks,) which came out in October of 2013.
#2) I'm not sending the lfr.safarietz file to you. I might consider it, if you'd apologize.
#3) The userscript "Textarea Backup with expiry" that I posted above does work just as well, if not better, than Lazarus did, with the latest version of Safari. Why do I suspect you haven't even tried it?
Start another thread for your inevitably-fruitless pursuit, perhaps? And please read carefully yourself, before criticizing people who are taking the time to help you.
Good luck to you and happy New Year.
