What it does
Iceraven is an independently maintained Firefox-for-Android derivative that expands configuration and extension choices.
Iceraven is aimed at users who want more choices than the standard Android Firefox interface exposes. Its repository describes a broader extension list and additional information about browser behavior. The maintained release series follows the Android browser with its own changes.
The project also warns that not every offered extension works and gives no stability or update guarantees. Choose a particular needed extension and verify its behavior rather than installing a large collection simply because the list is longer.
Release 2.49.0, based on Fenix 156, exposes site isolation at Settings > Customize > Others > Enable site isolation (Fission). The repository also warns that its refusal of prospective Android developer-verification requirements could affect availability on certified devices in 2026/2027. That is the project's stated distribution plan, so check its current release/install guidance before relying on a future device setup.
