From 4-week to 2-week:

We are planning to move Firefox Desktop and Android from a 4-week release cadence to a 2-week release cadence starting in September 2026.

But why... I don't even fully get why there is a dedicated cycle anyways. Just release an update when there is something worthwhile.

Maybe they should drop the AI and go back to 4.

They already produce nightly builds. Why are people upset that they feel confident to release stables every two weeks?

Fast release cycles might make sense for a new project that is in rapid development.

Fast release cycles for established products make no sense. What I want from a project that is tens of years old is primarily stability. They can do their internal releases at whichever pace they want, but don't push on users updates this frequently, it's just wrong.

This will be OK with me, as long as I don't have this popping up on a regular basis, forcing me to restart my browser:

[The Director at Mozilla] says: "We are planning to move Firefox Desktop and Android from a 4-week release cadence to a 2-week release cadence starting in September 2026. ... This will be an experiment. The goal is to give work that is ready to ship more frequent opportunities to reach users, while making the release process more predictable and reducing pressure on uplifts. .... The current target is to release Firefox 155 on September 1, 2026, instead of September 15."

Seems like a decent idea, wouldn't be able to say if it's a real improvement though.
