Video DownloadHelper is a featured Firefox add-on by mig. It has 1,950,154 daily active users and an average rating of 4.28. The latest version is 7.6.0 and was updated a month ago. Within Firefox Browser Add-ons, its overall ranking is #5.
Video DownloadHelper is the most complete tool for extracting videos and image files from websites and saving them to your hard drive.
Just surf the web as you normally do. When DownloadHelper detects embedded videos it can access for download, the toolbar icon highlights and a simple menu allows you to download files by simply clicking an item.
For instance, if you go to a YouTube page, you'll be able to download the video directly on your file system. It also works with most other popular video sites like DailyMotion, Facebook, Periscope, Vimeo, Twitch, Liveleak, Vine, UStream, Fox, Bloomberg, RAI, France 2-3, Break, Metacafe, and thousands of others.
Video DownloadHelper requires a lot of risky permissions and is not safe to use. Avoid installing
unless you absolutely trust this publisher.
Risk impact measures the level of extra permissions an extension has access to. A low risk impact
extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like
stealing your password, bypass your security settings, and access your personal data. High risk
impact extensions are not necessarily malicious. However, if they do turn
malicious, they can be very harmful.
Video DownloadHelper has earned a good reputation and can be trusted.
Risk likelihood measures the probability that a Firefox add-on may turn malicious.
This is determined by the publisher and the Firefox add-on reputation on Firefox Browser Add-ons,
the amount of time the Firefox add-on has been around, and other signals about the
Firefox add-on. Our algorithms are not perfect, and are subject to change as we
discover new ways to detect malicious extensions. We recommend that you always exercise caution
when installing a Firefox add-on, especially ones with higher risk impact and/or
higher risk likelihood.
It's mostly good when it works, which has been most of the time. JDownloader and Open Video Downloader seem to cover its gaps fine.
I have a minor issue and a major issue, though, causing this two star review.
First, the minor issue is that the "support site"/"forums" is a Google Groups conversation, except that's been blocked (by Google?) with a "Banned content warning". "Video DownloadHelper Q&A has been identified as containing spam, malware, or other malicious content." So you guys are getting this ugly feedback/"bug report" here.
Second, the major issue, for whatever reason, I'm pretty sure this plugin has been causing me major, major memory management issues in Firefox, especially with Twitch open. Basically, I leave a Twitch stream open for several hours (let's say 4+), close the tab, and the entire browser locks up for up to a minute (non-responsive program). I experience similar issues opening some media tabs during long and heavy browsing sessions without closing the browser.
This has also caused GPU driver crashes (AMD and nVidia) + crashing Discord, Hydrus, Path of Exile, Windows Explorer. Your extension is doing this! I don't know if it's a combination with something else, but I think this is the cause. This has been going on for years, across three graphics cards (AMD 290X, nVidia 970, nVidia 3070). The newer GPUs have been more resilient but that's only treating a symptom.
I have checked my computer with multiple memory management apps looking for anything that stands out: Task Manager (Processes and Performance), Resource Monitor, ProcessExplorer, RAMMap, Poolmon. I found some minor oddities that I've done my best to address, but the problem wasn't fixed. No issue in Chrome (does not have Video DownloadHelper). I tested Firefox on a clean profile with no issue. I started a new Firefox profile, but manually restored many parts of my old profile (dirty restore) with all my old extensions and the problem came back. I turned off half my extensions including this one, and the problem went away (for a few blissful months). I've since turned on a few of those extensions separately with no issue. Last night I turned on this extension too, and the problem is finally back.
As of typing this, I have one Twitch tab open right now. This browser session has been going for 12-24 hours, let's say. I check Video DownloadHelper's button in the Twitch tab. VDH is showing me 40 things I can download. 40! Most are streams, but I've only visited maybe 5 channels this entire browsing session. VDH shows multiple quality options for streams with transcoding, as it should. Some of these options are from tabs I closed hours ago. Some streamer avatars are mismatched. This can't be right.
I'm going to turn off your extension now. If I'm wrong I'll delete this report. I'm so tired of this.
The manifest file declares the requirements and permissions that
a Firefox add-on will have access to. By reviewing the manifest, you may be able
to determine if a Firefox add-on is over-reaching (for example, if an extension
is overriding your new tab page, or search provider, or requesting access to your web activities
without any good reason).
