Struct Profile 

pub struct Profile { /* private fields */ }

A Firefox profile directory.

Manages a Firefox profile, which contains settings, extensions, and state. Profiles can be temporary (auto-cleanup) or persistent (user-managed).

Temporary Profiles

Created with Profile::new_temp(), these are automatically deleted when the Profile is dropped.

Persistent Profiles

Created with Profile::from_path(), these persist after the program exits.

Implementations

impl Profile

pub fn new_temp() -> Result<Self>

Creates a new temporary profile.

The profile directory is created in the system temp directory with a unique name. It is automatically deleted when the Profile is dropped.

Errors

Returns an error if the temporary directory cannot be created.

Example

use firefox_webdriver::driver::profile::Profile;

let profile = Profile::new_temp()?;
println!("Profile at: {}", profile.path().display());

pub fn from_path(path: impl Into<PathBuf>) -> Result<Self>

Uses an existing profile directory.

If the directory doesn’t exist, it is created.

Arguments
