Private Tabs
Private tabs in Omni aren’t a label — they run in a separate GeckoView private context with real isolation.
Open a private tab
Tap + and choose New private tab, or press Ctrl Shift N. Private tabs are visually distinct and live in their own group in the switcher.
What’s isolated
- Cookies & site data — a separate, in-memory cookie jar.
- Cache — nothing is written to disk.
- History — private tabs don’t record history.
- Storage — localStorage/IndexedDB are ephemeral.
When the last private tab closes, all of it is gone.
Extensions in private tabs
Bundled extensions (Media Grabber, AI Blocker, Universal Copy) are allowed in private browsing by design — they run locally and send nothing out. Third-party extensions follow their own per-extension setting.
