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.

Requires an account to use.

The developer is condescending and purposefully unhelpful. Emailed Pauline and it was useless. You'll spend money to activate this extension and it doesn't work.

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!

Literally broke on the first link I tried.

Do not now yet

Amazing extension, works flawlessly!
