# Editing Filesets that have Revisions

## What

You may need to edit an existing Fileset after it has more than one revision. The revision selector controls which revision you are changing.

## When/Why

For example, assume a Firefox Fileset has two revisions: v79 and v80. You might need to change a file only in v80, or you might need to make the same change in both revisions. Check the revision selector before editing so you know which Fileset revision is open.

## How

In both the Fileset editor and the script editor, use the **Revision** drop-down menu to choose the revision you want to edit. In the screenshots below, the Fileset window is showing v79 and the script editor is showing v80:

To switch revisions in either window, change the value in the drop-down. If you do not use Fileset revisions, leave the selector at the default revision and continue editing the Fileset the usual way.
