I saw a bunch of 1 star reviews so I was like not sure about downloading it, but I did it anyway. Yeah it wasn't working at first, then I went to the add-on manager and told it to update this one specifically and now it works. UI is a little jank but it is working for me.

保存方法についてですが、ボタンを押すと画像を選ぶ画面になりますが、そこで複数選択できたこともありましたが、殆ど個別保存しか出来ず、同じ保存先のものだと手間がかかり過ぎであり、ましてや画像選択後の保存先を選ぶ画面も、パソコンの性能もあるとは思いますが、自分の場合画像がほとんど表示され無いので不要に思えるのである。
　結論としては、保存画像が複数選べて、後に保存先だけ選べたときの方が、使い勝手が良いのである。

tres bien

The Pinterest pop-ups (the save button and zoom button) that come up when you hover over a picture often block the "X" button to close out of something. For instance, if a site is running a sale, it might have a pop-up. I can't close out of it because the Pinterest add-on brings up these two buttons in the top of each corner of the image.

Works fine. I'd recommend you right click on the icon, select "manage extension" and then the "options" tab, and check the box that says "hide hovering buttons". They were constantly getting in the way of interface elements I was trying to click.

simples e prático.
