Doesn't detect anything until the Statistics bar completely fills up. I was in a web directory containing 9 images and after nearly 5 minutes of waiting, it says that out of 90k files (probably searched into the "Parent Directory" link), there are 0 images.
The 'tutorial' video contains no sound, not even a text-speech narrator.

Works well on Chrome but doesn't work at all on Firefox (I was trying to use it on Pixiv), on Chrome I can fine tune the settings to get what I need, but on Firefox it sees everything except what I need, no matter the settings I use, no restrictions, a level deeper, still nothing useful.
I tried the same exact link in both browsers with the same settings.

tried downloading a bunch of pictures (about 280 pictures from a board) from pinterest. it doesn't save most of the pictures even when you use search level 2 or 3. in fact, it saves a ton of duplicates & website assets. it also slowed down my computer (which is a modern high-spec pc that seldom lags) a lot to the point where i struggled to close firefox & use other apps. when i checked the task manager, i found out that firefox was using 95% of the memory. it usually doesn't use that much memory, so i suspect that it was the extension that was using up almost all of my pc's memory. also, it signed me out of youtube TWICE. not only that, but it signed me out of all of my email accounts. it's very creepy. DON'T USE THIS EXTENSION. it's pretty much useless even without the unprompted signing me out of all of my email accounts & memory hogging anyway. i truly don't understand how this is a recommended extension on firefox.

Exact what i was looking for in terms of functions and also clean, no clutter or nonsens fancy Gfx ui, just perfect.

Very useful add. Sometimes there are small flaws, but overall I give 4 stars
