Support status guide
End of life (EOL) is the end of a product’s useful life. When a product reaches the end of its life cycle, the manufacturer no longer supports it. The following table explains the different phases of a product’s lifecycle. Testing status is when the product is initially released and EOL is when product support is no longer offered. The time between these two points is the support timeframe.
Testing
The software is not yet publicly available. It is in testing phase i.e., alpha, beta, release preview etc.
Active
The software is actively supported by the vendor.
Phasing Out
The software will soon reach its end of life. You need to look for upgrade or migration options. The software will automatically go into phasing out status 2 months before end of life.
End Of Life
The software is no longer supported by the vendor. You need to make sure your system and environment are safe.

Mozilla Firefox is offered from different channels, where the mainstream stable channel receives a major update every 4 weeks. During those 4 weeks, Firefox may receive minor updates with no defined time intervals.
Other than that, Firefox is also offered in an Extended Support Release (ESR). It is the equivalent of the Long Term Servicing (LTS) channels many other software offer. The ESR channel receives major updates every 42 weeks and is designed for people who cannot adapt to frequent changes, such as developers. Firefox ESR does not come with the latest features, but it has the latest security and stability fixes.
Other than these stable channels, Firefox is also offered across 3 testing channels, or “Insider channels.”
- Firefox Beta: This channel offers a version number higher than the one being offered to the stable, regular Firefox channel. It includes some features that may be introduced to the stable release in the next update. The Beta channel may include some bugs, but usually, it is quite stable.
- Firefox Developer Edition: This channel is for the developers as this release includes more developer goodies than the ones available in the stable release, or the Beta release. This channel receives an update alongside the Beta version and has the same version number.
- Firefox Nightly: This channel is the equivalent of Chrome’s Canary channel as this channel receives daily updates. The new features and improvements are fresh off the developer’s plate and have not been completely tested. Therefore, this channel may have significant bugs. This is the first channel that receives an update, after which the selected features are passed on to the Beta channel, and then eventually to the stable release.
