Can't seem to install

[dennisTGC]

Firefox connection check fails after installation.

I'm running Ubuntu 22.04 (so still experimental for a month) and Firefox 98.

I'll try update this issue after 22.04 becomes LTS.

Is there any error on the installer.sh's output?

[dennisTGC]

No, not that I can see:

Installer is using the embedded NodeJS

It looks fine! Let's see if we can find something in the browser's console log.

Use Ctrl + J to open the browser console. Now try to use the extension and see if it generates a new error in the log section of the console.

Small correction... use Ctrl + Shift + J to open the browser console.

sorry it took a while, github had issues too..

xubuntu 20.04 same

[sverris]

Same here (Lubuntu, 22.04). Does not work for VLC and MPV anymore since yesterday. I switched to 22.04 beta yesterday. Wild guess: Firefox switched to snap, and I get the feeling that breaks something...

[andy-portmen]

as far as I know, a Snapped app is sandboxed to a single directory inside "~/snap/" directory. To have a valid native client, we need to copy the executable to this directory. Even though this fixes the communication issue, still not a useful approach. There is no way to access the external browser (it is located outside of the root directory).

I am attaching a working native client (x64 only) for testing purposes. Use Firefox with Ctrl + Shift + J to see the error logs.

[sverris]

Thanks. The new client does not help with MPV, but for VLC it does create a working connection. Yet the path for the VLC binary ( /snap/bin/vlc ?) is not correct - and whatever I try, it does not work.

[dennisTGC]

The connection works, but it can't find the executable, not even when filling in the correct path. Happens with brave and chromium-browser.

A directory was needed: -> Creating a directory at /home/user/snap/firefox/common/com.add0n.node => Native Host is installed in /home/user/snap/firefox/common/com.add0n.node ... -> Creating a directory at /home/user/snap/firefox/common/.mozilla/native-messaging-hosts -> Firefox Browser (snap version) is supported And ffmpeg installed to: /home/user/snap/firefox/common/ffmpeg

Now it works! Thanks very much!

Hi @andy-portmen,

thanks for your effort in providing this addon in the first place. I was about to type together my own little local extension but then ran into the problem of javascript opening an external application from firefox ...

Unfortunately I am one of those

Distributor ID:	Ubuntu
Description:	Ubuntu 22.04 LTS
Release:	22.04
Codename:	jammy

users who run into the problem that @sean1138 is describing.

I have also tried your provided hotfix but unfortunately that didn't help.

Note that I've installed nodejs prior to running the install.sh:

/usr/bin/node
NodeJS status = 0
Installer is using your system NodeJS.
...

but I still get the connection problem.

Any help in sight?

[jgsimard]

@andy-portmen @staerz any updates on this? I am on ubuntu 22.04 LTS. I got VLC and firefox from snap and it is not working

Nope.
