Support for NSS in latest firefox

I have run firefox and tried to figure out the dynamically linked ssl libraries.

pegasus@pegasus:~$ sudo lsof -p 21129 | grep -iE 'ssl|nss'
[sudo] password for pegasus: 
lsof: WARNING: can't stat() fuse.portal file system /run/user/1000/doc

If I add this path in libresolver.c:

const char *COMMON_PATHS[] = {
    "/opt/firefox/",
    "/home/linuxbrew/.linuxbrew/",
    "/lib/",
    "/lib64/",
    "/lib32/",
    "/usr/lib/",
    "/usr/lib64/",
    "/usr/lib32/",
    "/usr/local/lib/",
    
};

and compile and run the tool and visit any big websites, it gives segmentation fault.

Like this.
How to solve this?

clang: error: linker command failed with exit code 1 (use -v to see invocation)

When I'm trying to build the tools using make
