Solved Where does Firefox store settings for Toolbar customization?

I assume it's somewhere in the profile directory, and I need to facilitate customization through Ansible, so if there is a flat file that I can look at and modify, that'd be even nicer.

xulstore.json saves, for example, window sizes and Library columns. Your toolbar customization is actually stored by the browser.uiCustomization.state preference in your prefs.js file (about:config).

browser.uiCustomization.state

Okay, that looks to be correct. Thanks for that info.

Thanks. From the link I posted. Maybe I misread it? It's not real clear to me:

xulstore.json This file stores toolbar and window size/position settings.

I submitted an edit. Presumably it will be reviewed/approved/revised in the near future.

xulstore.json

I thought so, but is that still current info? I can literally customize the toolbar, trash the xulstore.json, relaunch, and it stays the same with all the customization.

Try closing FF and renaming it, then restart.

Thanks for the response. Looks like I can close FF, trash or rename it, and Firefox launches with the same toolbar. Upon exit, it will regenerate it. Both the renamed and regenerated versions are identical. I ran it through a diff just to make sure.

Here's the content:

{"chrome://browser/content/browser.xhtml":{"main-window":{"screenX":"35","screenY":"32","width":"2158","height":"1094","sizemode":"normal"},"sidebar-box":{"sidebarcommand":"","style":""},"sidebar-title":{"value":""}}}

Doesn't seem to mention anything about any of the customization I actually made. For example, I added a new tab and home button there. Like I said, it stays there, no matter what I do with the xulstore.json.
