Default preferences: How to set default zoom?

I'm wondering how to configure a default zoom level for all users.

I want

about:preferences -> Default zoom

to have a default value of 133% instead of 100%.

So far I'm using the files

firefox/distribution/distribution.ini

and

firefox/browser/defaults/preferences/all-XXX.js

for configuration, but I don't know which keyword to use. I compared the content-prefs.sqlite file between to test profiles, one having 100% default zoom, the other having 133% default zoom.

The database says there is a setting "browser.content.full-zoom", but I can't configure this with the *.ini or *.js file, or can I?


I also read this:

https://developer.mozilla.org/en-US/docs/Mozilla/Preferences/A_brief_guide_to_Mozilla_preferences

but it didn't help.

This global zoom setting isn't stored as a pref in about:config (prefs.js).

The default global Zoom value as set in "Options/Preferences -> General -> Zoom" is stored in the content-prefs.sqlite database under settings -> browser.content.full-zoom that links via the 'settingID' to prefs -> value

Some settings can be set programmatically using JavaScript in an Autoconfig file. This particular setting is fairly new so I don't think I've seen code to set it. Also, perhaps you don't want to override a setting the user may have customized? Well, perhaps is not worth the time, but if it's a high priority, perhaps it is worth pursuing.
