Original GitHub issue: https://github.com/netblue30/firejail/issues/1717

So I saw the --private-lib option and decided to play around with it a bit, but I couldn't actually get it to like me. Using the firefox profile attached, I decided to try firejail --profile=.config/firejail/firefox.profile --private-lib=firefox sh and it gave me this output:

Error: failed to run /usr/lib/x86_64-linux-gnu/firejail/fldd
Error: proc 21880 cannot sync with peer: unexpected EOF
Peer 21881 unexpectedly exited with status 1

The thing is, those libraries are in /usr/lib/firefox, and even including x86_64-linux-gnu/firejail in the --private-lib path (which...shouldn't it already be included?) didn't help. I know I'm using --private-lib wrong, I just don't know why.
TIA!

Please retry with --debug, that should tell a bit more what's happening.

fslib_copy_libs firefox
cannot find firefox for private-lib, skipping...

This means that "firefox" can't be accessed. Is it in your $PATH? Is /usr/lib/firefox a program, directory or symlink? What's output of
ls -ld /usr/{bin,lib}/firefox
?

/usr/lib/firefox is the directory containing the libraries necessary for firefox to work. The actual binary is /usr/bin/firefox. Both exist as shown by:

*chiraag@chiraag@17:50:-100%:~ $ ls -ld /usr/{bin,lib}/firefox
lrwxrwxrwx  1 root root   22 Jan  5 02:19 /usr/bin/firefox -> ../lib/firefox/firefox
drwxr-xr-x. 7 root root 4096 Jan  6 18:37 /usr/lib/firefox

If I don't use private-lib, everything loads fine, which implies firefox is in my path and everything else is dandy (and, indeed, it is).

I don't know if it matters where I install firejail, but I installed it to /usr/local and it didn't fix the problem (yes, firejail is actually running the one from git, not the distro-installed one - I checked). I will try overwriting the distro-installed version and see if that helps.

So firefox starts up just fine. But trying to actually open any pages (other than about:-style pages) results in the URL bar losing focus and no site actually loading. Since I don't get any error messages from --debug-private-lib, I'm not sure what exactly is going on (it's probably a library problem, but...no error messages).

But trying to actually open any pages (other than `about:`-style pages) results in the URL bar losing focus and no site actually loading. Since I don't get any error messages from `--debug-private-lib`, I'm not sure what exactly is going on (it's probably a library problem, but...no error messages).

The solution is given in #1920 (which also provides a mostly automatic way to generate the required library list). Closing this.
