Been using a while, works well for what i use it for.
This is the only one so far, that reliably gets updated if it goes down. If it goes down they have it up and running again pretty quick.

They're are problems but Dishita sure is staying on top of them and correcting them <5-stars>

Great extension for download videos from youtube

I've been using this converter exclusively since its inception.It Has never let me down. I'd like to personally by Dishita a dinner some day. add it on,you wont be disappointed.

Thank you for being so on top of the updates! The add-on is excellent quality and although I don't use it regularly, it has always functioned properly when I needed it.

Thank you again for the amazing work! YouTube is constantly changing so I imagine it's pretty challenging keeping up with it all the time.

So glad I came across this! It couldn't be easier to use, and it works! I can't use enough exclams over this! The dev updates the code frequently in response to the YT service's whack-a-mole suppression campaign. If you don't get the results you expect, drop them a line and let them know. Things get fixed fast.

Writing this to support a dedicated developer who constantly works to keep up with all of the YT changes in order to allow us to keep downloading... big thank you!

Developer keeps pumping out updates whenever YouTube tries to break this add-on. Good work! If this add-on doesn't work, install the latest version, clear the cache and restart Firefox!

it works now! before it didnt but now it does! im rating it four and not five because you have to pay for a lot of features and it doesnt always work, but its the best extension i have tried!

This extension actually works, however, It is almost impossible to locate the real downloading URL location/button because the author has liberally added adverts which look as though they would be the download URL for this (good) firefox add-on. For instance, I just received an email touting an improvement to this add-on, but was unable to locate the download url to it.
UPDATE: improvements no longer have to be downloaded, since they automatically are installed by this extension.
If you can find the URL for the Author's support email, you will actually get a response in about 3 days. My experience is that if you don't give up after receiving the first, generalized response, you will eventually be very satisfied by the author's support, e.g., it took me 4-5 emails to get exactly the information I was seeking.

This addon worked for me all the time. Great content provided from the developers, thank you very much!

Amazing

It works, even when YouTube changes his code.
