作品単体しか不可能

Does not work. There is no download button.

A few days ago it worked perfect for me and now that I reinstall the browser, the download icon no longer appears even when reloading the page!

Does not work on firefox android. All it does is create empty folders without downloading any images.

Happened regardless of whether or not permissions allow for downloads.

Addon can't even be installed on the non-nightly firefox build

I'm not sure how this add-on is supposed to work, but based off of the reviews and screenshots, I'm either supposed to have a pop-up appear or an option to download whenever I view someone's work on Pixiv. Neither these or any other options have shown up, so I'm assuming this extension doesn't work as of version 3.4.4.

「↓PX Downloder」が出なくなった。

全くうごイラ保存出来ませんねぇ…
もう無理なのでしょうか

複数枚の画像がDLできなっています。このまま対応する予定はないのでしょうか？

Does not save multiple images (simply lies "Done"), has no hotkey for downloading.

Where the heck does this download too? I never see any popups when it finishes "fetching/processing" and I can find no option in the settings for it.
