266508 - updating firefox with setup will create multiple windows software entries

Status: VERIFIED DUPLICATE of bug 247884

(Firefox :: Installer, defect)

Description

[Mark Janssen]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.3) Gecko/20041026 Firefox/1.0RC1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.3) Gecko/20041026 Firefox/1.0RC1

When updating Firefox with the .exe installer on Windows, it will create
multiple entries in the software panel, for example:
Mozilla Firefox (0.9.3)
Mozilla Firefox (1.0PR)
When updating via the zip file, there will still be an old entry (e.g. "Mozilla
Firefox (0.9.3)" when 1.0PR is installed) in the software list.

This occurs also in Mozilla Thunderbird.

Reproducible: Always
Steps to Reproduce:
1. Install an old version of Firefox or Thunderbird
2. Install a newer version

Actual Results:  
Two entries were created in the software menu.

Expected Results:  
One of the following:
* Remove the old entry
* Create a non-version specific entry (e.g. "Mozilla Firefox" without version)
so the entry gets overwritten automatically
* Automatically uninstall the old Mozilla Firefox version before installing the
new one

A workaround is using the zip files to install Firefox (every time) or
uninstalling the old version before updating.

Same behaviour when upgrading from Firefox 1.0 to Firefox 1.0.1. Please change
status to NEW.

There's already a bug for this.
