This addon is meant to be used with a rebrandly account, which you can get for free. It makes shortlinks quick, and even lets you change the /slug to whatever you want, right from the addon window. The only downside is that the addon doesn't have a dark mode.

The best link shortener I have ever found. I could really recommend using Rebrandly!

This program allows editing the destination URL of previously created links. This is exactly what I was looking for. I've used bit.ly and tiny.url, which are great, but at the time of this review they require a subscription to do that. Rebrand.ly seems to be the only program that can do this. Great stuff!

Do not now yet

Amazing extension, works flawlessly!
