This should not have been recommended to replace DownThemAll!, it is a disgrace and dishonor to DTA. This is nothing like the latter. Its annoying that we need to click on its icon before it can start grabbing stuff. I've used other extensions (other than DTA) without the need to do this (they just automatically grab stuff). The interface itself is not user friendly. I expected that the column would sort the list but nothing changed when I clicked on it (list was still unsorted). I also expected that checkboxing a certain type of media would filter the list instead of just checking all of that media in the list. Personally, it was an eyesore to see the list not aligned to the column. It does not even grab all the videos I expected it to. Firefox Developer Tools does this better (in terms of listing stuff). I mean, I can see the link of a video in the Network tab of the Developer Tool so I expected this add-on would grab it but no, the video does not appear in its list. This add-on is also not non-electrolysis (non-e10s) friendly. I believe that the reason for it to kinda freeze (opening to a blank window), as what happened to everybody else was because e10s was disabled. Personally, for the time being (before a new DTA gets released), I'd recommend Video DownloandHelper. At least using VDH feels way better than using this.
