永遠にログインできないエラー出てるみたいですね

It sucks. Keeps asking to sign in, even though it is.

Не могу сохранить, требует авторизоваться. Захожу, но все равно не сохраняет.

Не сохраняет, а каждый раз предлагает войти в аккаунт. Каждый раз вхожу, но всё равно ничего не сохраняет.
Doesn't save pictures, offers authentication. After authentication everything is the same.

Just straight up didn't function at all

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

El botón no funciona.

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

лично у меня не работает

Slowed down the browser immensely.

Doesn't work

does'nt work half of the time...

Just didn't work at all for me.

Hit & miss whether it works or not ... and Pinterest should have no business accessing my bookmarks.

As others have mentioned, what's with the new permission to "Add and modify bookmarks"? No thank you.

Since the last update, Pinterest has deleted the option to modify the description of your pin directly when you pin it, I'll have to go to my pin board and modify the pin there afterwards, which is a lot of hassle. This makes the pins i get from my tumblr likes untraceable. It bothers me, because pinterest as a platform is already terrible at giving artists credit or exposure and now I feel like I'm contributing even more when I am updating my own boards. Please fix this ASAP.

This just doesn't work. The button was red when I first installed it. Clicking it did not do anything.

I'm using Firefox 80.0 on Windows 10.0.19041.450 running on a Lenovo P53 workstation.
