[Mozilla Enterprise] Downgrade Protection and Profile Per Installation in Firefox 68

[James Pearson]

Could you explain what is meant by 'profiles per installation' ?

We use Firefox (on Linux) by installing each new release of ESR in a separate directory - which is available to all clients over NFS and use a wrapper script to select which version to run (by default, it uses the most recent version)

With ESR 68 and above, will each of our separate installs require a separate profile ? - or does 'installation' in this context mean Nightly, Beta, ESR, etc ?

Thanks

James Pearson

The best explanation is here:

https://groups.google.com/forum/#!topic/mozilla.dev.platform/hVeJSYjSnO4

(although it references Firefox 65 - this landed in Firefox 67)

We blogged about it here as well:

https://blog.nightly.mozilla.org/2019/01/14/moving-to-a-profile-per-install-architecture/

Support info for profiles per installation is here:

Is there a page with details on how these new features work?  I don't know enough about the proposals to know whether we are affected.

With Firefox 68 two new features are being added; dedicated profiles per Firefox installation and downgrade protection. These allow for simpler on-boarding of beta and nightly users and also prevent users from hitting profile corruption issues when switching between different versions/channels of Firefox.

Environment variables will be available in Firefox 68 to disable both features and we are assessing whether this will be enough for ESR users to maintain compatibility with their custom deployment configurations.

It would be great if you could let us know of specific issues related to these features that an environment variable would not allow addressing.

Thanks for your input.
