Objective

Make 64-bit Firefox the default version for new and existing eligible users to reduce our OOM crash rate, increase performance, and improve security (ASLR).

Users are eligible for a 64-bit default if they are running 64-bit Windows 7+ and have strictly more than 2 GB RAM (so 3 GB is effectively the minimum memory requirement). For users with less than 4 GB of physical memory, there is a trade-off between the larger virtual address space and the overhead of 64-bit code. 2 GB RAM is Microsoft's minimum memory requirement for Windows 7 and 10.

Which Firefox versions will be migrated to 64-bit?

  • 32-bit Firefox <= 55.0.3 will be updated to 32-bit 56.0, a watershed release for all users on all platforms.
  • 32-bit Firefox 56.0 will be migrated to the latest 64-bit release (currently 56.0.2). Only users running exactly 56.0 are eligible for migration.
  • 32-bit Firefox >= 56.0.1 will be updated to the latest 32-bit release (currently 56.0.2), but will not be migrated. If you were migrated to 64-bit but want 32-bit, you can install 32-bit 56.0.1 or later and not be re-migrated.

Release Criteria

Migration Opt-Out

Users running 32-bit Firefox on Win64 OS with at least 2 GB RAM will be automatically upgraded/migrated to 64-bit Firefox 56.0.1. 32-bit Firefox users that do not wish to be migrated to 64-bit Firefox can opt-out of the migration setting a Windows registry key (added in bug 1386176) as described below.

If you have already been migrated to 64-bit Firefox 56.0.1 but prefer to run 32-bit Firefox, you can download 32-bit Windows Firefox 56.0.1 and re-install. Firefox will not attempt to migrate 32-bit users running version 56.0.1 or later!

Instructions for creating the migration opt-out registry key:

  • To disable migration for all Firefox installations on a client system for all users, create the following registry entry:
    • Path: HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla\Firefox\32to64DidMigrate
    • Value Type: DWORD (32 bit) Value
    • Value Name: Never
    • Value: 1
  • To disable migration for all Firefox installations on a client system only for the current user, create the following registry entry:
    • Path: HKEY_CURRENT_USER\SOFTWARE\Mozilla\Firefox\32to64DidMigrate
    • Value Type: DWORD (32 bit) Value
    • Value Name: Never
    • Value: 1
  • To disable migration for a single Firefox installation on a client system for all users, create the following registry entry:
    • Path: HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla\Firefox\32to64DidMigrate
    • Value Type: DWORD (32 bit) Value
    • Value Name: <Windows path to the installation directory without a trailing backslash> (Important: do NOT include a trailing backslash!)
      • example: C:\Program Files (x86)\Mozilla Firefox
    • Value: 1
  • To disable migration for a single Firefox installation on a client system only for the current user, create the following registry entry:
    • Path: HKEY_CURRENT_USER\SOFTWARE\Mozilla\Firefox\32to64DidMigrate
    • Value Type: DWORD (32 bit) Value
    • Value Name: <Windows path to the installation directory without a trailing backslash> (Important: do NOT include a trailing backslash!)
      • example: C:\Program Files (x86)\Mozilla Firefox
    • Value: 1
