Firefox ESR Config

[anverhousseini]

Hi

Im trying to create a deployable configuration for Firefox ESR. So far so good but I cannot suppress the "Import settings from another browser" dialog. What I tried so far:

pref("profile.confirm_automigration", true);
pref("profile.migration_behavior", 0);
pref("profile.migration_directory", "");
pref("network.cookie.prefsMigrated", true);
pref("profile.allow_automigration", true);

Any ideas?

Hey @anverhousseini

Unfortunately I have no experience modifying the ESR directly, but we use CCK2 for our customization. You can find it here: https://mike.kaply.com/cck2/
It should modify everything you need, then it spits out an autoconfig that you bake into Firefox.
Mike Kaply offers paid support for it if need be but the tool itself is completely free.
In fact, he was so good at it that he was hired by Mozilla.

Hi @jrippy

Thanks! Yes I tried that, but it seems it doesn't work anymore with version 45. I tried it myself but Firefox is crashing all the time. Can you confirm this?

[jrippy]

@anverhousseini No I can't confirm that. We're running 45.3.0 ESR in our labs without issue.
We don't do a lot with CCK2 but we do skip all the initial prompts and bookmark stuff, etc.

@jrippy it could be, that I misplaced the files. Could you please give a hint where to place following files/folders from the autoconfig folder?

• browser
• cck2
• defaults

Thanks!

@anverhousseini Sure. Looking back at my notes, here's where the files and folders go.
Put browser/* in Firefox.app/Contents/Resources/browser/
Put cck2/ in Firefox.app/Contents/Resources/
Put cck2.config in Firefox.app/Contents/Resources/
Put defaults/pref/autoconfig.js in Firefox.app/Contents/Resources/defaults/pref/
