Wrong permissions, editor not starting

[ingo-h]

I installed textern following the Installation instructions. But the editor (gvim) does not open when I hit Ctrl+Shift+D. After looking what's going wrong I realized that native files have no global read permission. This is because I do not use the default umask 022 on my system for reasons. Instead I use umask 007. That means new created directories and files have the permission rw-rw---- on my system.

I have tried to correct (I would not like to set absolute permissions e.g. chmod 644):

sudo find /usr/lib64 -type d -exec chmod o+rx {} \;
sudo chmod o+r /usr/lib64/mozilla/native-messaging-hosts/textern.json
sudo find /usr/local/libexec -type d -exec chmod o+rx {} \;
sudo find /usr/local/libexec -type f -exec chmod o+r {} \;
sudo chmod o+x /usr/local/libexec/textern/textern.py

But this is not enough. If I install textern for the current user then everything is working.

What is to do to run textern system wide in this case?

It's hard to say to be honest. I run with the default umask here so haven't hit this. Is it Firefox complaining it can't start the native app or is it the native app complaining it can't e.g. read the tmpfile?

[ingo-h]

In the browser console I get:

No such native application textern  NativeMessaging.jsm:99
    NativeApp</this.startupPromise< resource://gre/modules/NativeMessaging.jsm:99:9

Where is the tmpfile located?

[jlebon]

OK, right, that indeed sounds like it can't find/execute Textern. To confirm, is Firefox installed under /usr? Or /usr/local or e.g. ~/bin?

[ingo-h]

~$ which firefox
/usr/bin/firefox
~$ lsb_release -d
Description:    Debian GNU/Linux 9.5 (stretch)

Firefox is installed from the default repositories, no special.

[ingo-h]

Just for testing I have started firefox as root but get the same error message in the browser console.

[ingo-h]

I have found what's wrong. Seems firefox on Debian only looks at
/usr/lib/mozilla/native-messaging-hosts/textern.json
for the native messaging manifest and does not know
/usr/lib64/mozilla/native-messaging-hosts/textern.json
the installation is made. Reference: Manifest location. I will make a pull request.
