Raptor DownloaderInstall in Chrome, Edge or Brave
Add the Raptor Downloader extension by hand in about a minute, until it is listed in the stores.
Download and unzip
Download the extension (ZIP). Right-click the
file, choose Extract All, and extract it to a folder you will keep, for example Documents\Raptor Extension.
The browser loads the extension from this folder, so do not delete it.
Turn on Developer mode
Chrome and Brave: the switch at the top right. Edge: the switch in the left column.
Load the folder
Click Load unpacked and choose the folder you extracted (the one that contains manifest.json).
Raptor Downloader appears in the list.
Pin it
Click the puzzle-piece icon next to the address bar and pin Raptor Downloader, so its button is always visible.
Seeing a message about developer mode?
Chrome may ask whether to keep extensions in developer mode when it starts. Choose to keep it. This message disappears once the extension is in the Chrome Web Store.
Update it
Download the new ZIP, extract it over the same folder (replace the files), then on the extensions page click the reload arrow on Raptor Downloader.
