I am guessing the bad reviews are mostly from non-technical users who simply don't know what is going on. This is one of the most powerful extensions available and is absolutely essential. I admit I have only used it on chrome but after testing it on Firefox it seems to be just as powerful and useful.

Looks like its the best one for my user case at least(Javs etc). Video DownloadHelper does okay too, but don't detect video streams as well as this one.

As others have said, the UI could be slicker, but it does what other extensions cannot for grabbing segmented (m3u8) video files

So far this is the best built in video downloader i've ever used. It beat IDM and jdownloader. Thanks to developer who create this amazing tool. I wonder if I'm have few bucks, I'll make a donation.

The interface is a bit clunky, but it does its job perfectly!

OMG.OMG. OMG. I have been searching tirelessly and this is the only streaming extension that works on the sites I need to download. If only you can find a workaround YT which recently added protection and we can't download. Otherwise, for other sites, Chandler, you're AWESOME!!

Where all else (extensions) fails, this add-on comes through - whether of a live-stream or streaming (mu3) or regular mp4 video - without fail. Only quibble is that the interface or menu isn't as familiar as other downloading apps, and the interface could appear complicated with technical listings (video often referenced as a code of numbers and letters than understandable words). But if you can decipher (even guess) the lines, it's a reliable app to download videos even when standard downloading apps stumble and fail, especially with the streaming videos.

It's seem to be best vdo downloader for me now but it's not ideal user-friendly. I prefer the program ask me at first place where to save the file and what name it is, not after the downloads is complete. So many times the downloading takes hours and i cannot wait until the end. The program should save the file automatically or give an option after downloads. To sleep or shut down the computer.

Works perfect on my machine. The bad reviews are probably people who don't know how to computer.

in all honesty f*** vdhcoapp! this works flawlessly

It actually works in conditions where other addons fail. Can download videos that you can't even download normally when looking into source code and such.

It's working, uses the browser's default download location, seems pretty good.

Ya have to know what to do. I mean you have to really know what you're doing and it will work. Try things. Trying things like right clicking on the video ;)

It's a great addon for Firefox, but the last version that works with 155.13.0esr (32 bit) is 0.4.7.3. Version 0.4.8 always displays a blank dialog when the toolbar button is clicked.

I downgraded back to 0.4.7.3 and all is well again.

This thing works so good and so fast. I got this app to use where video downloadhelper didnt work (actually a great number of sites) This is going to be my primary program. This one is so much better!!! great work!!
