Identify how Firefox was installed
Mozilla’s update guidance distinguishes its usual browser update flow from Firefox installed through a Linux distribution’s package manager. Determine which route supplied this installation. The correct updater depends on that provenance, so an absent browser-level setting is not automatically a damaged profile or an account restriction.
Use About Firefox where applicable
For the documented direct-update flow, open About Firefox through the browser’s Help or Firefox menu. Mozilla says the browser checks for updates and downloads an available release, followed by Restart to update Firefox. Save unfinished work before restarting rather than closing an active form or account operation without preparation.
Respect the package-managed case
Mozilla says Linux distribution installations receive updates through the system’s software updates and do not show the browser update options. Use the distribution’s supported package route for that installation. Do not install a second unrelated copy merely to make a missing button appear; that can create different versions and profiles that confuse the original diagnosis.
Record the actual result
After completing the appropriate update process, inspect the running version and reproduce the original issue briefly. Keep the packaging route in the support description. A package-manager result and a browser About result are evidence about software state; neither establishes service entitlement or guarantees that a specific player website supports the newly running release.
Questions, answered
Why might Linux Firefox have no in-browser update option?
Mozilla says distribution-managed builds update through the system package manager.
Is downloading an update always the final step?
No. The documented direct flow applies it after restarting Firefox.
