Bitly has a disappointing extension. You can't finish creating a short without first creating a tag or assigning one. If you want to create a tag during short creation, you can't do it. You have to go to the website to create new tags.

Excellent add on while it was free, now they charge for more than 12 links a month, it´s cool, they have the right to charge, i have the right to go for a free shortener.

New UI/UX is not helpful and now requires scrolling even with my large vertical screen. :( Previous version was much easier to use. Is there a way to revert to the previous version?

Works great, but the toolbar icon isn't Retina quality. Looks pixelated. Seems like this shouldn't happen in 2018.

No longer works on FF 57+
