Make Storage cleaning when closing Firefox. And delete that weird GIF from there.

I explain reason. For many, the profile is backup automatically, and the extra 3 MB turns into many gigabytes when there are many backups.
Delete manually saved images does not work, the extension stops working.

In this case, I will be happy to use your addition.

Pretty good. Lost a couple stars because all the links I added have disappeared on both home/work PCs.

Many useful features!

Easy to use and customize!

Excellent.

非常好的一个扩展，图片都很养眼，更棒的是所有的图片都能免费下载！
