1. After the U.I. of Video DownloadHelper was updated, voiced and half-voiced marks are no longer added to Japanese file names.
Also, the first character of the file name [Mosaic Destruction] automatically changes to Mosaic.
Returning to Legacy U.I. will restore normality.
2. After using the new "Installed companion app: VdhCoApp 2.0.19", when a download error occurs, it is no longer clear which video is causing the error.
I would appreciate it if you could fix the above two points.

インターフェイスが変更されて手間が一つ増えた感がある。
それより問題なのは、ダウンロードしたファイル名が変更されてしまう不具合がある。
日本語の濁音、半濁音は全て濁音なしになる。
例）「が」→「か」、「ペ」→「へ」
通常は起こりえない変換なので、意図的にやってるとしか思えない。
記号や句読点、果てはカンマやピリオドもすべて消える。
保存されるファイル名は全て使い物にならない。
また、サイトによってはダウンロードできなくなる。

悪いことは言わないので、Ver.8.2.2.8を試して欲しい。
これは上記の不満がすべて解消される素晴らしいアドオンだ。
Ver.9は使い物にならないが、8.2.2.8ならきっと素晴らしいネットライフを送れるはずだ。

porque aparece ahora marca de agua???
cuando la extension era (obsoleta ) o nueva era mas facil con el auxiliar que se descargaba y ahora que "mejoro" en su ultima updated al parecer empeoro.
es triste ver que las cosas las dañan por intereses de "cualquier indole$" per deberian retirar la marca de agua que aparece al descargar los videos.
si dañan la alicacion lo mas probale es que se preparen para archivarla.
amo la aplicacion pero cuando comienzan los desarrolladores a cometer errores en contra del usuario .... es cuando toca abandonarlos.

Ruining a good app. A hopeless layout, disturbing pop-up side bar (i dont know how back to download in menu icon) and useless download application that creates many problems. There is no history in browser!, you can't go to the file, you can't see when you download it in browser etc. The application is currently too annoying, so I decided to use another one.

I remember it working quite well, now it has a qr code covering approximately 1/6th of the video. It looks like it now requires a $30 fee to remove the QR code, which probably not worth it for my usage cases.

Bien para muchas páginas, pero en YT no funciona.

ставит сторонний софт, на самое плохое делает вотермарк в видео.... удалил это расширение.

good

Tem que ter um app secundário para baixar o vídeo, mas em vez de estar disponível pela loja segura ele pede pra baixar do site deles. Pode ser seguro mas por ser muitos passos já não é um app vídeo downloader.

This once was the king of all add-ons. With the latest updates there are major errors especially with the companion app, which leaves this add-on no longer usable across many platforms. Too bad.

als ze werkt is het een mooi ding, maar er zijn meer problemen met deze addon dan dat ze werkt. en ik kan begrijpen dat men sommige video's beveiligt en dat de manier van handelen eerst moet achterhaald worden, maar als ik betaal voor een licentie zou ik graag hebben dat ze werkt naar behoren en niet "SOMS" een jaar later en ettelijke updates... lijkt het alsof steeds minder kan downloaden of dat ze steeds minder videofiles vindt... en nu moet je nog toestemming geven. voor wat? donno... converteren van lokale files? wel een knop maar niks in de plaats

I agree with all the recent opinions. This was a wonderful download app until I accidentally updated. Now it is hit or miss whether the desired video shows up in the download choices. I also prefer to have the firefox processor download the video and not the DownloadHelper Companion App as it errors out 30-40% of the time. But this most recent Helper update ignores my selection of Browser processor instead of Companion App processor. This version has too many bugs in it. Will be seeking another download app if these aren't fixed.

As others have noted, the most recent updates have rendered a formerly great extension quite unreliable. I'm giving it three stars with the expectation that things are likely to get better, but as of now it's really worth only two, as it works about a third of the time. [Edit: Down to two stars. The frequent failures render it essentially worthless now.]

Used to be really good, easily 4 or 5 star. Is still very good when it works, but recent updates have made it very inconsistent and I'd say about 70% of my downloads fail now or download up to a few MB. The other 30% that succeeds downloads much faster, but it's pretty annoying having to close my browser completely to refresh a page and try a new download (Before the update, a failed download only needed me to refresh the page and then I could try again)

This used to be an immaculate video downloader. BUt the recent update has ruined it. HLS media often doesn't start downloading even if you refresh the page and start downloading multiple times. And now in most web pages, the video is downloaded without names and instead with random video titles. If the devs are just gonna ruin this extension with subsequent updates, just stop updating it smh

the new version(8.2.1.1) put a giant QR code on the downloaded video, wish the dev wouldve clarify it in the description

Hi. The "Copy address" simply don't works. It doesn't add anything, not even with thirdy-part software (like CopyQ). I swap back to version 8.1.4.0 and all copy address works, as usual. Regards.
Windows 10 Home (22H2) updated
Firefox 122.0.1
Update:
I can't ear audio when I copy and past a url from YT to any video player (VLC, SMPlayer, PotPlayer etc.). With old addon version all works fine.
With Firefox I fix the problem simply by reinstall old version but in Chrome is impossible to find it. Please provide dowload of old version for Chrome users. PLEASE!
