Thanks, overall the changes on the js side look good!
Two things I noticed:
- Most of these changes still need some
#ifdef MOZ_ENTERPRISE-ing. - The code that handles external links and requests new windows is very distributed. I think a new module that centralizes all that logic would help.

Let's export these flags here and import them wherever needed (e.g. in browser/base/content/nonbrowser-mac.js and browser/extensions/felt/api.js). Maybe also wrap them in an enum?
export const FELT_OPEN_WINDOW_DISPOSITION = {
DEFAULT : 0,
NEW_WINDOW : 1,
NEW_PRIVATE_WINDOW : 2,
}

| if (isFeltUI) { |

Could we delcare isFeltUI closer to its usage? Or actually, since it's only used once, we could generally drop the variable and call Services.felt.isFeltUI(); directly.

Maybe also leave a log message console.warn(`Retrying to queue url ${payload.url} after initial failure.`);
Extend the URL opening IPC with a flag indicating where to open things.
Prevent users from triggering new window/private window actions before Firefox is ready by implementing platform-native blocking: - macOS: Grey out dock menu items until ready - Windows: Block jump list until ready (uses existing blockJumpList mechanism) - Linux: Show notification when action is queued before ready Adds felt-firefox-window-ready observer notification that fires when both firefoxReady and extensionReady are true.
Move the pending URL queue (gFeltPendingURLs), disposition constants (FELT_OPEN_WINDOW_DISPOSITION), and queueFeltURL function from BrowserContentHandler.sys.mjs into a dedicated FeltURLHandler.sys.mjs module. This improves code organization and makes the URL handling logic more maintainable. Update all consumers to import from the new module location.
