Video DownloadHelper includes a feature called Smart Naming. It allows to rename automatically the video filebeing downloaded from text within the page that contains the video.

Firefox Extension Called Download Helper
Video DownloadHelper is a browser extension software. As such, it relies on an interface providedby the browser (API) to its extensions to do the job. Chrome and Firefox (>=57) provide exclusivelyan API called WebExtensions that do not include a number of things required by VideoDownloadHelper to do all the tasks. In particular, WebExtensions has no real support for writing files properly. After many discussions with Mozilla (the Firefox editors) engineers, it appeared that the only solution for providing the service was to install an external application aside of the browser.
Fortunately, WebExtension provides the ability to launch a specific application and communicate with it, it's called Native messaging. This is a secure interface that ensures no other extension can take advantage of the coapp for performing any malicious activity.
If the former did not work for you, then there is a good chance Video DownloadHelper did notdownloaded the media properly. Nowadays, it is very common for web sites to stream separatelyaudio and video, with a web page player resynchronizing both channels. Video DownloadHelper tries to accomodate standard methods for aggregating audio and video, like in HLS or DASH protocols, but sometimes, the web site used a homemade method and our extension has no clue on how to reunite both streams. In this case, sorry but we should consider Video DownloadHelper just does not workfor this site.
Hi vishvas, I cannot recreate your problem: I am able to download the file and to pass the chesum validation.I assume that the download of the file extension.xpi on your installation attempt was corrupted and the therefore the checksum validation failed.Please retry the installation and let me know if the issue still persists.
I found over the weekend that there is also a "Download with Web Browser" option that can work instead of using the companion app. Just proceed as normal, when the download begins, a dialogue window will popup prompting you to download the helper. But next to this is a button marked "Download with Web Browser" (or suchlike). Just click that.
You can use this extension to do more than simply download any videos from YouTube, however. Video Download Helper can also make file conversions, such as converting between WEBM and MP4 formats, for example.
All you need to do to make the most of YouTube Downloader WebX is to install the extension and begin browsing. Once it detects a YouTube video embedded in a page, the extension will let you download it easily and painlessly.
This answer is not a duplicate of something already answered, since i'm asking specifically for regarding downloadhelper firefox extension, and a mysterious problem of audio only, specific to this clip.

A Firefox extension is a type of software that extends the capabilities of your Firefox browser. Extensions are comparable to apps on your phone, except they're for your web browser. Once you download a Firefox extension, it'll appear at the top of your browser, near the address bar.
Extensions may be used to enhance your browsing privacy, customize your interface, organize your tabs, and more. In this case, we are going to discuss extensions that allow you to download videos through Firefox.
Unlike Firefox extensions, video downloaders are not directly associated with your Firefox browser. Instead, they're a separate software and can typically be used with any web browser (i.e., Chrome, Firefox, Internet Explorer).
They still require downloading, but the application will be located on your computer rather than within your browser's interface. High-quality video downloaders offer significantly more capabilities and features than Firefox browser extensions, including being able to download videos in higher resolutions and the ability to switch file formats.

Consider whether you want to download a video downloader or a Firefox extension. A Firefox extension is easy to use but has limited capabilities. In contrast, a high-quality video downloader offers a wide range of features, more efficient downloading, and higher resolutions.
Some web browser extensions will only work for YouTube-hosted/served videos. In contrast, other approaches/tools/methods listed/mentioned here (in this article/page('s contents)) will not work for identifying and downloading (extracting/obtaining) YoutTube videos.
A web browser extension (not a plugin) can be installed within the web browser.To download videos from YouTube, you probably need Firefox (not Chrome) (for this purpose).
The makers of SaveFrom offer official web-browser extensions for the various major web browsers. This is referred to as the SaveFrom.net Helper and it offers all of the capabilities (features) that are offered by the website version of their service (software) (mentioned above, previously), plus more (in some cases). Particularly, the full range / gamut of files that YouTube servers offer (including separate audio and video-only files of various bit-rates and encoding formats) can be accessed with the browser extension. In other words, the extension offers more choices of files to download than the SaveFrom.net website does.
Like SaveFrom's web browser extension (previously-mentioned / see above), this isn't like a typical HTTP-traffic video-file sniffer (that detects whatever files are culled/pulled from a server by ActionScript / Adobe Flash technology .swf animations.) Instead, this functions like all other YouTube video file downloaders, by making A.P.I. calls to YouTube's servers. (In other words, it is yet another tool that makes use of YouTube's API. It doesn't matter whether your web browser has the Adobe Flash plugin installed or disabled or blocked or not (you use HTMl5 video).) 2ff7e9595c
