DO NOT INSTALL!
This addon is not maintained anymore by its developer. It redirects you to a porn site

DO NOT EVER INSTALL THIS ADD-ON!
Immediately after installing the extension, it redirects me to a porn website called scorchin.com (don't open it yourself!)
I have reported this to Mozilla

Great add-on, I like it, but I miss whitelist/allowlist feature because it is annoying how this add-on blocks gmail and other false positives everytime! For instance, it thinks https://mail.google.com/ is a short link. Please fix that.

This has worked perfectly up till recently, now anytime I use a link to youtube either in my bookmarks or the search bar I go to unshort.link every time unless I'm watching a video. Still was good up till then, assume FF update broke this.

It just works. Props for the dev for creating this!

Essentially - it works.

Even if unshort.link was to track their users, the local code is Free software, and they aren't in the business of buying and selling data the same way egregious sites like bitly do.

Only complaint is that since it is a web service, they should really be using the AGPL (license) for server and local code. I have not inspected the server code at all.

I like that it is set and forget. It intercepts automatically if I open a short link. The process of adding new short link providers via the website is a bit inconvenient though.
