Older versions of firefox - can't find the executable

Hi Folks,

Our security team, as well as Bigfix, are reporting several Windows 7 workstations with older versions of Firefox installed, as well as the latest version that I pushed out.

These older versions are not in the Add/Remove Programs list, and I assume they are somewhere within a user’s profile.

I did a search for firefox.exe from the root of C:, and that search only resulted in the firefox.exe that is part of the deployed version I sent out. So, I assume it is just some files out there that need to be deleted.

Anyone know where to find these files? For the workstation with firefox 40.0.3 listed, I assume I could run waithidden wmic product where name=“Mozilla Firefox 40.0.3 (x86 en-US)” call uninstall /nointeractive.

Thanks for any replies, my fellow BigFix addicts(or at least being paid to use it).

Hi Sam,

Which version was reported? Can you find any evidence that this version is actually installed on the device?

If you are not able to find the old version, the report could be caused by the registry key entry [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\firefox.exe]. Under this key there should be values indicating the path to the exe.

We had an issue with a number of machines having the “FrontMotion” version of firefox installed (A GPO manageable fork of the installer I believe).

We used the following relevance to detect it:

exists keys whose (value "Publisher" of it is "FrontMotion" and value "DisplayName" of it as string contains "Firefox") of key "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall" of x32 registry as string

Thanks folks. I’ll look and see what I can find.
