semanage fcontext -a -t firefox_var_cache_t "/var/cache/gecko(/.*)?" restorecon -Rv /var/cache/gecko Even with "extra quality" intentions, you may encounter errors. Here’s how to resolve them: Error 1: Gecko cannot write to profile: Permission denied Cause: You set 700 , but the Gecko process runs as a different user (e.g., geckodriver runs as selenium user). Fix: Use ACLs instead of basic UNIX permissions: # /usr/lib/tmpfiles

# Use 2750 (drwxr-s---) for extra quality sharing chmod 2750 /var/cache/gecko chown root:gecko-team /var/cache/gecko For Systemd-tmpfiles (to persist on reboot): Here’s how to resolve them: Error 1: Gecko

A security tool like Lynis or OSSEC reports: Directory /home/user/.mozilla/firefox/ has permissions 755. Extra quality hardening required. The fix: chmod 750 /home/user/.mozilla/firefox and enforce strict group membership. Part 5: Achieving "Extra Quality" with Gecko and drwxr-xr-x You can transform a standard, vulnerable drwxr-xr-x Gecko directory into an "extra quality" hardened asset. Follow this workflow: Step 1: Identify All Gecko Directories find /home -type d -name ".mozilla" -exec ls -ld {} \; find /opt -type d -name "firefox" -exec ls -ld {} \; Step 2: Assess Current Permissions stat -c "%a %n" /home/user/.mozilla/firefox/*.default If you see 755 , proceed to hardening. Step 3: Apply Extra Quality Hardening # Remove "others" execute (prevents traversal) chmod o-x /home/user/.mozilla/firefox/*.default Remove group read/execute unless needed chmod g-rx /home/user/.mozilla/firefox/*.default Final permission: 700 (drwx------) chmod 700 /home/user/.mozilla/firefox/*.default

setfacl -m u:selenium:rwx /home/user/.mozilla/firefox/*.default Cause: A cron job or systemd service resets permissions. Fix: Grep for chmod in startup scripts:

For directories that must be shared (e.g., a system-wide Gecko cache in /var/cache/gecko ):
