Subject: Re: Switching 32- to 64-bit installation (win) & profile problem...
To: <tb-ent...@mozilla.org>

I have just been working on upgrading FF 32-bit to 64-bit and thought I would document my findings.

When doing a silent install of FF 64-bit on a machine with an existing 32-bit install, FF 64 is installed

into C:\Program Files\Mozilla Firefox and the existing 32-bit install remains in C:\Program Files (x86)\Mozilla Firefox,

and both installs are listed in Programs and Features, and can be launched separately. FF 64 will create a new profile.

When running the GUI 64-bit installer, the installer detects the existing 32-bit install, and will perform an in-place upgrade,

converting the 32-bit installation to 64-bit. This is evidenced by the confirmation button in the GUI being named Upgrade, 

rather than Install, and when choosing to customize the install, the install directory is pre-filled as C:\Program Files (x86)\Mozilla Firefox.

To perform an in-place upgrade silently, one can set the install directory path on the command line (from Firefox v62 onwards) e.g.

/InstallDirectoryPath="C:\Program Files (x86)\Mozilla Firefox"

As far as I can tell, this performs a successful in-place upgrade from 32-bit to 64-bit FF retaining use of the same profile.

(Although, yes, there is the downside of having 64-bit binaries living in Program Files (x86).)

HTH,

Dafydd

               Mike,

 

If we’re changing from 32-bit to 64-bit, Firefox won’t be in the same directory (C:\Program Files, instead of C:\Program Files (x86).  The profile, however, sould be in the same directory.  And I only used 80.0.1 because I couldn’t find another 32-bit version.

 

 

Regards,

Steve

               Hello,

 

We are currently packaging 78.2.0 ESR 64-bit for our internal electronic software distribution, and during my testing of the package, I notice that if I install over a 32-bit version of Firefox (like 80.0.1) and I have saved bookmarks, after installing 64-bit, those bookmarks are gone.  Is there a to preserve bookmarks when upgrading from 32-bit to 64-bit?

 

Are you installing into the same directory? It definitely should keep those. Although it looks like you are doing a downgrade (80 to 72) which should be giving an error.

 

 

In the past we had used the MOZ_LEGACY_PROFILES=1 value in environment variables to get the bookmarks, but it appears that no longer works.

 

Downgrades use a different variable:

 

From https://support.mozilla.org/en-US/kb/understanding-depth-profile-installation

 

The downgrade blocking can be bypassed by setting the environment variable MOZ_ALLOW_DOWNGRADE or by passing the --allow-downgrade command line argument when running Firefox.

 

How can we make sure that users don’t lose their bookmarks and other settings when upgrading from 32-bit to 64-bit?  Thanks.
