CoApp Not Recognized in LibreWolf - Linux Flatpak

[ufgkirk]

Your question

I just installed the CoApp on my Linux system, and it is working in Firefox, but not in LibreWolf. Based on the output of the installer, it looks like the registration of LibreWolf was just skipped by the installer.

LibreWolf was installed from a Flatpak. I am running a KDE Plasma environment on Debian 12.

Browser version:

$ flatpak list | grep LibreWolf
LibreWolf io.gitlab.librewolf-community 128.0.3-2 stable system

OS Version:

$ lsb_release -a

To uninstall, run '/.local/share/vdhcoapp/vdhcoapp uninstall' and remove '~/.local/share/vdhcoapp'.
Re-run that script to update the coapp.

Based on some discussion I found in another post here about this issue on Mac OS, I tried copying the native-messaging-hosts folder from the Firefox directory to the LibreWolf directory, but this had no effect for me.

~/.var/app$ ls org.mozilla.firefox/.mozilla/native-messaging-hosts/
net.downloadhelper.coapp.json
~/.var/app$ cp -R org.mozilla.firefox/.mozilla/native-messaging-hosts io.gitlab.librewolf-community/.librewolf/
$ ls io.gitlab.librewolf-community/.librewolf/native-messaging-hosts/
net.downloadhelper.coapp.json

Vdhcoapp info dump:

$ ~/.local/share/vdhcoapp/vdhcoapp --info
{
"id": "net.downloadhelper.coapp",
"name": "VdhCoApp",

Hopefully it will be an easy fix, and maybe the installers can be updated to support LibreWolf in the future. Thanks!

Do you recall seeing a popup in the browser to give it permission to access the companion app. I have a screenshot of it for the
Firefox snap app on Ubuntu. You can see that it popped up after I opened the settings in the extension.

Hmm.... unfortunately no.

I gave this a try, but it seems to have had no effect.

I actually did try the recommended solution in that other thread of copying folders from my .mozilla folder for my Firefox install into the .librewolf folder. It had no effect either. lol

[bitsByB]

same problem for firefox here too...

It seems like the default installer puts a net.downloadhelper.coapp.json files to the directories of almost all mainstream browsers and Librewolf isn't one of them. The solution is to copy the file into librewolf's folder manually to make it work:
/home/user/.mozilla/native-messaging-hosts/net.downloadhelper.coapp.json
/home/user/.librewolf/native-messaging-hosts/net.downloadhelper.coapp.json
