[Linux] Chrome / Chromium extension not detecting application

[yochananmarqos]

I installed launcher-manifest-chrome.json as /etc/chromium/native-messaging-hosts/DownRightNow.json for Chromium and /etc/opt/chrome/native-messaging-hosts/DownRightNow.json for Chrome, but neither detect the application in /opt/downzemall/. However, I also installed launcher-manifest-firefox.json as /usr/lib/mozilla/native-messaging-hosts/DownRightNow.json and Firefox detects it.

  "path": "/opt/downzemall/launcher",

I just updated to 2.0.4 and updated the extension manually since it's not yet available on the Chrome web store. Same deal.

EDIT: Forgot to mention, I'm the AUR package maintainer.

I just saw the AUR link. Nice work!

It's a bit cumbersome to install the app on Linux. At the moment there are still opened issues (especially to make a valid AppImage..), so it's great to see you achieved to install it (at least manually) on ArchLinux and it worked.

FYI sometimes the web-extension addon is in a lower version (for instance 2.0.3) while the app is in a more recent version (like 2.0.4). It's ok, because the addon didn't change between v2.0.3 and v2.0.4. The addon's upgrade on the Firefox/Chrome webstores isn't automatic, and generally I don't make the effort to upgrade when the change concerns the version number only. This decision pattern could be called a lazy non-upgrade.

If you need anything, let me know.

Copying it to ~/.config/chromium/NativeMessagingHosts/ doesn't work. All the other extensions I have installed that place files in either place work fine.

❯ ls /etc/chromium/native-messaging-hosts
DownRightNow.json  io.keybase.kbnm.json  me.f1u77y.web_media_controller.json  org.gnome.chrome_gnome_shell.json  org.gnome.shell.extensions.gsconnect.json

Maybe rename the file to "com.setvisible.downrightnow.json" instead of "DownRightNow.json"

full path : ~/.config/chromium/NativeMessagingHosts/com.setvisible.downrightnow.json

For Firefox, it's a different convention:
~/.mozilla/native-messaging-hosts/DownRightNow.json

For info:

• Firefox, read last section of
  https://wiki.mozilla.org/WebExtensions/Native_Messaging

• Chromium:

Aha! That fixes it. I've updated the AUR package.
