Updates & channels01

What updates your Firefox installation?

The update route depends on where the browser came from. Identify the installation before following another set of instructions.

Source-checked guide
Updates & channels02

Firefox Release or ESR?

Choose by the feature changes and compatibility work you can maintain. A channel change is not a diagnosis of a browser problem.

Source-checked guide
Bookmarks & data04

Bookmarks missing after an update?

Check visibility, the active profile and available copies before you restore anything. “After an update” describes timing, not a proven cause.

Troubleshooting06

One website is broken in Firefox

Use the exact symptom to choose a scoped test. A page working in another browser is useful evidence, but it does not identify the faulty component.

BEFORE YOU CHANGE ANYTHING

Your browser and your data
are different things.

A new installation, a different profile and a reset can look similar from the outside. Their consequences differ. Identify the state you want to keep before choosing an action.
