Install manually, without Terminal

Prefer not to run a command? Download the extension as a ZIP file and add it to your browser yourself. It takes about two minutes. Pick your device below and follow the pictures.

Download the extension

⬇ Download MiraiSub (.zip)

The file comes only from miraisub.com. Never install a MiraiSub file you got from somewhere else.

  1. Download the ZIP file

    Click the download button above. The file subapp-private.zip is saved to your Downloads folder.

    miraisub.com/install/manual/⬇ MiraiSub .zipsubapp-private.zip4 MB · Downloads
  2. Extract the ZIP file

    Open the Downloads folder, right-click subapp-private.zip and choose “Extract All…”, then “Extract”. A folder named subapp-private appears. Move it somewhere you will keep (for example Documents): the browser loads the extension from this folder, so do not delete it.

  3. Open the extensions page

    In the address bar type chrome://extensions and press Enter. In Edge type edge://extensions, in Brave brave://extensions, in Opera opera://extensions. Cốc Cốc also accepts chrome://extensions.

  4. Turn on Developer mode

    Switch on “Developer mode”. In Chrome, Brave and Cốc Cốc the switch is in the top-right corner; in Edge it is in the left menu. It only lets you load an extension from a folder.

  5. Click “Load unpacked”

    A new row of buttons appears. Click “Load unpacked”.

  6. Choose the subapp-private folder

    Select the subapp-private folder you extracted (the one that contains manifest.json, not the ZIP file) and confirm. MiraiSub now shows in the list and its welcome page opens.

Updating to a new version

  1. Download the new ZIP from this page.
  2. Extract it and replace the contents of your old subapp-private folder (same place).
  3. Open the extensions page and click the reload ↻ icon on the MiraiSub card. Your sign-in and settings are kept.

Common problems

“Manifest file is missing or unreadable”

You picked the wrong folder or the ZIP file itself. Choose the folder that directly contains manifest.json; if it is nested, open it one level deeper.

The browser shows a warning about developer mode extensions

That is normal for any extension loaded from a folder. Close the message; MiraiSub keeps working.

MiraiSub disappeared after I deleted or moved the folder

The browser reads the extension from that folder. Put the folder back (or extract the ZIP again) and load it once more.

I don’t see “Load unpacked”

Developer mode is still off. Turn it on, then the button appears.
