AdGuard Japanese filter prevents the CAPTCHA dialog from appearing on avgle.com, resulting in the video not playing.
If necessary, please add the following filter to [My Filters] to show CAPTCHA dialog.
avgle.com#@#body > div[style*="z-index"]:not([id]):not([class])

• Bookmarklet and usage is posted on my blog. https://avotoko.blogspot.com/2020/04/avgle-hls-playlist-downloader.html
• Tested on firefox + ublock origin.

1. Open the video page in browser.
2. Run avgle-hls-playlist-downloader.js (as bookmarklet.)
   ref. Run avgleHPD using Greasemonkey.
3. Click close button overlapping the video. In March 2022 uBO hides the close button. In that case, click play button.
4. [Download HLS Playlist] button will appear when the playlist is successfully retrieved and decrypted.
5. Click the button and download avgle.m3u8.
6. You can play the video using Streamlink.
   streamlink --http-header Referer=https://avgle.com/ file://<location>/avgle.m3u8 best
   Or you can download the video.
   streamlink --http-header Referer=https://avgle.com/ file://<location>/avgle.m3u8 best -o video.ts
   • The url described in the playlist(m3u8 file) retrieved by AvgleHPD becomes inaccessible after a while.
     Try to run Streamlink as soon as possible after retrieving the playlist.
   • You must specify the url instead of the local path of m3u8 file.
     How to convert local path to url: https://en.wikipedia.org/wiki/File_URI_scheme
     [Example for Windows]
      downloaded file path: c:\temp\avgle.m3u8
      url: file:///c:/temp/avgle.m3u8
      command line:
      streamlink --http-header referer=https://avgle.com/ file:///c:/temp/avgle.m3u8 best

• Outputs errors and other information to the console of the browser's developer tools.

You can define the function avglehpdPreDownload separately to change the file name to be downloaded.
