Just a thought, but can you run sudo chown [your username] user.js and see what happens?
Thanks

authentication failed
The user is owner of the file and I put write also for group wheel and I have options now to change the file.
Again edit: doas chow 'my user' user.js it happened nothing

The first time when I ru updater.sh and prefsCleaner.sh both works but lthe next time the problem.
I use clone github and download zip file and it is the same.

Can you run ls -l user.js prefs.js updater.sh prefsCleaner.sh and see what it returns?
Thanks

ls -l user.js prefs.js updater.sh prefsCleaner.sh
-rw------- 1 aj aj 27680 Nov 23 15:35 prefs.js
-rwxr-xr-x 1 aj aj 6167 Nov 23 12:52 prefsCleaner.sh
-rwxr-xr-x 1 aj aj 13953 Nov 23 12:52 updater.sh
-rw-r--r-- 1 aj aj 74634 Nov 23 12:52 user.js

Thanks. That's bizarre. If I read that correctly, you should be able to modify those files.
Maybe someone smarter has an answer.

Can you please run ls -l user.js prefs.js updater.sh prefsCleaner.sh before and after running updater.sh and prefsCleaner.sh?

`prefsCleaner.sh canot start:
./prefsCleaner.sh
It looks like this script was previously run with elevated privileges,
you will need to change ownership of the following files to your user:
./user.js

Please also show us the command you're using to run these scripts. Are you running them as root or user aj?

I am running as user aj.
Before:
-rw------- 1 aj aj 27845 Nov 24 05:19 prefs.js
-rwxr-xr-x 1 aj aj 6167 Nov 23 12:52 prefsCleaner.sh
-rwxr-xr-x 1 aj aj 13953 Nov 23 12:52 updater.sh
-rw-r--r-- 1 aj aj 74634 Nov 23 12:52 user.js

After I run ./updater.sh which works now:
-rw------- 1 aj aj 27845 Nov 24 05:19 prefs.js
-rwxr-xr-x 1 aj aj 6167 Nov 23 12:52 prefsCleaner.sh
-rwxr-xr-x 1 aj aj 13953 Nov 23 12:52 updater.sh
-rw------- 1 aj wheel 75403 Nov 24 05:31 user.js

and now i the problem:
./prefsCleaner.sh

./user.js

I do not know why changing user.js aj to wheel?

Thank you for your time.

Did you changed your primary group to wheel rather than adding wheel as supplementary group?

What does id show?

Hi,

I removed the check for "is group == root/wheel" in both scripts, because it's probably enough to check the user only.
I don't think Firefox will mind either, as long as the user has read permissions on these files.

If you have auto-update enabled, both scripts should update themselves and the problem should be fixed.
Otherwise just update both scripts manually.

I assume this worked? closing - feel free to ping me if it doesn't work
