Gecko Drwxr-xr-x [HD]

ls -ld ~/.mozilla/firefox/*.default/startupCache/gecko Output:

chmod 700 gecko # drwx------ – only owner can access gecko drwxr-xr-x

ls -ld /usr/lib/geckodriver/gecko You might see drwxr-xr-x permissions on a directory named “gecko” that holds platform-specific binaries or resources. Modern Linux distributions (Ubuntu, Fedora) often package Firefox as a Snap or Flatpak. Inside their restricted filesystems, you can encounter: ls -ld ~/

ls -l /usr/local/bin/geckodriver But if you examine support directories: gecko drwxr-xr-x

chmod 755 gecko # drwxr-xr-x After changes, restart Firefox or your Selenium script. While not crucial to permissions, it’s worth noting: the Gecko engine was named after the gecko lizard , known for its ability to cling to surfaces. The idea was that the browser engine would “stick to web standards” just like a gecko sticks to walls.
