I have this: /home/jose/.local/opt/buster and in the manifest: /home/jose/.mozilla/ native-messaging-hosts

Is the space in the manifest path intentional? I have deleted your other issue, please don't open new ones when someone doesn't respond right away.

[gitanopro]

I have tried with and without space and it doesn't work

[dessant]

Is your Firefox profile at /home/jose/.mozilla or are you using a profile from a custom location? That space should not have been in the manifest path, try installing without modifying the default values.

[gitanopro]

I have not changed the profile path, I have tried to install with the user defaul, the one that is created with newly installed firefox and nothing

PD: in the path you say I don't see any profile file, should it point to the profiles?

[dessant]

There should be a manifest file at /home/jose/.mozilla/native-messaging-hosts/org.buster.client.json. Did the installer successfully create the manifest? If yes, please share the contents of the file, and also check if there is an executable at /home/jose/.local/opt/buster/buster-client and make sure that the Execute checkbox is set for the executable in Properties > Permissions.

[gitanopro]

file content org.buster.client.json : { "name": "org.buster.client", "description": "Buster", "path": "/home/jose/.local/opt/buster/buster-client", "type": "stdio", "allowed_extensions": [ "{e58d3966-3d76-4cd9-8552-1582fbc800c1}" ] }

2. the executable exists and has execution permissions

[dessant]

I'm not sure what went wrong, everything seems to be in place.

[dessant]

What is the path you see on the about:support page for Profile Directory?

[gitanopro]

the path shown is: /home/jose/snap/firefox/common/.mozilla/firefox/9266edcv.default

[dessant]

Ok, we've discovered the origin of the issue: Firefox is installed using a Snap package. It seems Snap and Flatpak packages break browser extensions that use Native Messaging because of file system isolation.

https://bugzilla.mozilla.org/show_bug.cgi?id=1462888 https://bugzilla.mozilla.org/show_bug.cgi?id=1621763

The easiest workaround is to install the browser from a traditional distro package, without Snap or Flatpak. If you don't want to lose your browsing data, you could either use Firefox Sync, or copy your Firefox profile folder to the default location.

I still have the same problem, but when uninstalling firefox and installing the logs they have changed

Now you're running the browser as root, the client app will only install if the browser and the installer are not executed with root.

[gitanopro]

can you give me instructions on how to do that? I have not understood you very well and I do not know how to do it

[dessant]

You can simply start the browser on Ubuntu from the app icon, and it will run as the current user instead of root. Same with the client app installer, just double-click on it after you've made it executable, and it should run as the current user.

I don't have enough information about your OS to understand what you're doing wrong, but this doesn't look like an extension bug at this point.

[gitanopro]

My current user is root, what you tell me is not working, I don't know what could be happening

[dessant]

Are you trying to install on a server? In any case, try asking around on an Ubuntu support forum if you have installed it on a regular PC, tell them that your current user is root and you'd like to use the default user created by Ubuntu, and they'll be able to help you.

[gitanopro]

I have installed it on a server, what should I do now?

[dessant]

Try asking for help on the Ubuntu support forum.
