Flash Video Downloader for Mozilla Firefox

Last Updated: Nov 03, 2017 12:34PM EDT

As soon as you install Flash Video Downloader plugin, new buttons depicting blue arrows will appear on top and bottom panels of your Mozilla Firefox Internet browser.
You will be able to download the video with the help of these buttons.

Why do some videos have an inscription saying Convert instead of Download and I'm offered to download a module?

Firefox, starting from version 57, changed the API, and now the old methods of downloading FullHD videos and Live Streams no longer work. We were compelled to create a special separate module processing video fragments and joining them together.

There is no need to download this module if you are not planning to download FullHD videos or Live Streams.

Hmm… And what if this module contains viruses?

Before downloading, you are welcome to run your antivirus. The module also gets checked by Mozilla editors.

Another important aspect to mention is that the module file is signed with the company's special key.

How to install the module?

You just need to download the module from the site and run it. Further installation process is the same as for any other program. Once the installation is completed, restart your Firefox browser. After that, you can download the videos.

Can I delete the module after installing it?

Yes, the module can be deleted just like any other program.

How to download video?

Open the page with the video and click Play. Click on the add-on button (it must turn blue)
and in the window that appears, click on the video you need to download.

You can also switch to Full Mode, where you will be able to view full links to video files. You will also have the possibility of downloading multiple files at a time.

Why do I get a DOS window when downloading a video?

Some  websites  may feed video and audio as two different files and so those  have  to  be joined in advance. You need FFMPEG for that. That's exactly what you see launching (to join the files) after the download is initiated.

The video is playing, but the button remains red. Why can that be?

In all likelihood, this is a licensed video that can't be downloaded from the site, or there are technical restrictions (for instance, the RTMP format may be used).

Go View - Toolbars - Customize, then find our button and drag it to the add-on panel.
