Original repo author rejected the PR for Firefox support, so the owner of the fork did just that - fork to add 6 lines of manifest:

https://github.com/jswanner/DontF-WithPaste/pull/29

(I admit though that the unrelated .gitignore change had nothing to do in the original PR)

Well, this is for firefox, and the other is for Chrome, so maybe that's a significant upgrade?

IMO upvotes are due more to a "Yes, I agree, hate when that happens" than a "Thank you for this useful tool OP"

The fork is for supporting Firefox, which I consider to be a significant upgrade as I don't use Chrome in the first place. You can see the original repo easily, but it's far more annoying with GitHub to find a particular fork. I can keep it to myself next time if it offends you that much though, no reason to tell other people on HN about something I found interesting.

Oh yes, 3 files changed compared to parent and the changes are gitignore and updated URLs to the forked repo.

yep. Quite the WTF
