The problem that the screen freezes when the download panel is displayed is occurring again.
At this time, the only solution to this problem is to revert to version 1.6 or earlier.
The download speed will be greatly reduced, but let's accept it as it can't be helped now.

The button under the player is hidden again, but it is possible to call the download panel from the button in the toolbar of the browser.
If the download panel doesn't finish loading, lowering the version to 1.1.7.2 may help.
By the way, the download speed issue has also been resolved since 1.1.7.2.

(The above is a translation of Japanese into English using Google Translate.)

The developer must be asleep. I had to revert to 1.1.5 to get the app to work. Why he broke the app and has not fixed it is beyond me. I turned off automatic updates for the app.

Mysteriously, the app updated itself even though I had turned updates off. Naturally, it quit working. It seems very resistant to having 1.1.15 installed and you have to be quick so it does not auto update. I had to try three times this time to get it to install.

I would like to know what the developer is doing!

[update 1.25.2022]
1.1.7.2 stopped working for me yesterday, the download button had disappeared again a couple days ago, no probs I could use the toolbar shortcut, but since yesterday the DL links won't populate, the entire tab will lock up and firefox will display "this tab is slowing down your browser". 1.1.8 doesn't work for me; rolling back to 1.1.6 technically works, I get the links and can download, but the speeds are basically useless, again back to downloading at like 50KB/s, which takes forever for even a small video.

I REALLY DO DESPISE GOOGLE AND YOUTUBE.

estaba funcionando bien pero la actualizaron y ahora no sirve nada, estoy a punto de mejor desinstalarla

Starting from version 1.18 this app no longer works. Sad trash.

Siempre me ha gustado esta extension pero ultimamente no ha estado muy eficiente. No esta bajando los videos y no se cual es el problema.

One of the BEST and MOST CRUCIAL Firefox addons EVER! Happily using for years!
(Especially now that recent problems have been fixed.)

not working

beautiful app!!! thank you. But 1.1.8 doesnt work..when older ones yes!!!!

Update on 2022-01-22:
1.1.8 doesn't work for me so I had to go back to 1.1.7.2 by (1) scrolling down on the addon's main page until "Version History" is seen (2) clicking on "See all versions" (3) finding older version 1.1.7.2 and clicking link below it "Download File"

Original review from 4 years ago:
I have used this so much for archiving youtube-only content. It works fantastically and cleanly. I used to use Flashgot, but this is an adequate replacement (since I mostly need downloads from youtube).

Thank you RayLo!

Stopped working after 2022.01.13 update.
I loved this add-on because of not only it's the fastest downloader that i've used to work together with turbo downloader add-on (up to 3Mbps vs 82 to 150kbps with Easy Downloader), but also with the clever and neat placement of the download icon. Unlike other that just put a Download button with the word "download" bigger that other things you'll ever see in the page.

I hope this works again on the next update. Will be patient with the other downloader but will keep checking for updates on this every time i can.

FireFox 97 (64-bits); ADD-ON 1.2.1; Its fully works now

It works in 1.1.7.2(previous release of this addon) with the latest firefox version.
You can open download panel through toolbar.

It doesn't download anything. Useless.

sranje ne deluje

me encanta, lo mejor que he tenido en este tipo de app

This used to be an amazing tool, except since the latest release it no longer works. Please address this situation. I used to love this add-on.
