Close Private Tabs Automatically in the Firefox iPhone App can be handled directly on a current iPhone, although some menu names have changed since older iOS versions. The steps below focus on the current interface and note important differences where they matter.
Steps to use the current setting
- Open Firefox and tap the menu button.
- Tap Settings.
- Under Privacy, use Close Private Tabs to control whether private tabs are automatically removed when you leave private browsing or quit Firefox.
Private browsing keeps Firefox from saving normal browsing history, cookies, and searches for that private session, but it does not make you anonymous to websites, your network provider, or an employer or school network.
What to know
These instructions are written for current iPhone software rather than preserving an outdated model-specific path. If your device runs an older iOS release, the same feature may appear one level higher in Settings or use slightly different wording.
If privacy is the goal, remember that leaving private tabs open can expose them to someone who later unlocks the phone. Closing the tabs when you finish is the most predictable approach regardless of any automatic-close preference.
