Firefox Unbranded
Mozilla's official alternative to Mozilla Firefox, with ability to install unsigned addons in release version
Unbranded builds are available from the continuous integration builds on treeherder.mozilla.org.
What is different compared to Nightly and Developer editions (which allow unsigned addons too)?
It is stable or release version that allows unsigned addons, unlike those two unstable/experimental ones.
Same version is released whenever stable Firefox is released.
They work just like Firefox, with two differences: they have a setting to disable mandatory signature checks, and they don't have the Firefox name and logo (instead using a generic name and logo). These builds are available in the en-US locale only.
