问题1：保存图片虽然设定了上下左右拖动对应的功能，但实际用的时候是混乱的。
问题2：拖拽的时候鼠标后跟着⊘符号（但能打开链接），⊘可代表死链或者拖拽不成功，每次用的时候就很容易误判不知到底是什么情况，感觉好违和。所以卸载不用了。
Problem 1：although have configured 4-direction actions for dragging images, the add-on is confused with each other when using.
Problem 2: when dragging, the cursor is followed by ⊘ while the links can be opened. The symbol ⊘ is usually for an invalid link or a failed dragging. It's so confusing and misleading.

Doesn't work in FF multitask mode.

It is working, but the Save image to folder is missing yet, hope you can make it happen in the near future.
