i want updatemy mozilla firefox

Hi there,

To update Firefox to the the latest version, please check out:

• Update Firefox to the latest release (desktop Firefox)
• Update to the latest version of Firefox for Android

You appear to have old package build of Firefox 88.0 on a flavour of Ubuntu Linux distro.

If there are nor more Firefox package updates in yopur package manager then this likely means your version of Ubuntu is EOL is software package updates.

So to get Firefox package updates you need to update to a current version of Linux distro. Or you could use the Firefox Linux tarballs from Mozilla as it gets internal updates from Mozilla like the macOS and Windows versions do. You just need to make sure the Firefox folder has read/write permissions for the user to get Firefox updates.
