It simply did not work. which is a real shame as it always worked on Chrome.

I love it when it works.

El botón no funciona.

Comes in Handy once in awhile

It's been working fine for me for years, but a few days ago it became completely non-functioning and I'm sick of trying to troubleshoot it.

The button never worked for me—I'd click the button and nothing would happen.

The icon on the upper right is annoying. It is exactly where some pop ups have the close ("X") button. It is also at the exactly same place as the Watch Later button in YouTube, so it is hard to use YT's button because of Pinterest's icon with the magnifying glass.

Stop auto scrolling to the top in twitter when we pin images in there.

Nine times out of ten it doesn't work so it gets a 1/10

Works well most of the time, but on Youtube this prevents use of the 'watch later' function by covering it. Would be great if the developers could either fix this or allow turning off the button on certain websites.

It's so slow to use and super clunky. I though it would just save it but it opens another window and takes forever to load.
