This extension sometimes causes the screen to flash white, in particular after clicking the toolbar button. In addition, the buttons appearing everywhere are irritating, especially on Youtube thumbnails. I would recommend to use an unofficial extension instead.

could not get it to work

This is ridiculous, I can't add it to my Firefox! Mozilla people need to fix this button so we can add it... ASAP

Can't get save button to add to browser. Useless to me.

Two years later and it still barely works.

A complete disaster of an extension. It never selects the business account boards only the personal account one. Uninstalled

I have tried numerable times to download this extension and I cannot do it. I had the Pinterest pin previously and it was a simple process. Frustrated. Adding to this six months later, no one from Fire Fox has given any advice.

El botón ha dejado de funcionar en Firefox. no reconoce la cuenta con que se ha iniciado sesión y por lo tanto no te aparecen los tableros en los que insertar el pin. Si cambias de cuenta, la extensión se bloquea.

This button makes everything unclickable

Does NOT work. At All. No matter what I try it will Not save pins, and all it does is freeze my browser window. Useless. But judging from all the other bad reviews, they have no intention of fixing this.

It was a time this add-on worked like a charm but now no... :'(

Nothing works now. Followed all the instructions and still cannot pin from other sites.

This Pinterest button simply doesn't work on Firefox. The pinterest window opens in a format so large I can't even get on it, and it doesn't move around and can't be sized down. Given the ratings I'm seeing, you should really be fixing this...you're going to lose customers.

got suspended from pinterest for using this

straight up does not work. clicking the pin button does nothing.

The latest version doesnt work on Firefox.
The only way to do this is to uninstall the latest version, clean the cache/cookies, close Firefox and reopen it and install an older version (4.1.108 works fine on my PC).
la dernière version ne fonctionne pas sur Firefox.
La seule façon de faire est de désinstaller la dernière version, nettoyer les cookies/cache, fermer Firefox et rouvrir, et installer une ancienne version (la 4.1.108 fonctionne bien sur mon PC).
