There are some 20-ish strings here:

browser/locales/en-US/chrome/browser/places/editBookmarkOverlay.dtd

They are used exclusively from https://searchfox.org/mozilla-central/source/browser/components/places/content/editBookmarkPanel.inc.xhtml

The new ftl should live in https://searchfox.org/mozilla-central/source/browser/locales/en-US/browser/ .

The included .xhtml content gets used in 3 places, see https://searchfox.org/mozilla-central/search?q=editbookmarkpanel.inc.&case=false&regexp=false&path=

In all except browser-doctype.inc, these can just be added as regular .ftl links in the files that are including the .inc.xhtml file.

In the browser-doctype case, it should be possible to remove the DTD reference, and then use MozXULElement.insertFTLIfNeeded() to insert the .ftl from https://searchfox.org/mozilla-central/rev/c80fa7258c935223fe319c5345b58eae85d4c6ae/browser/base/content/browser-places.js#306 , without adding it as a fixed .ftl link in browser.xhtml. We should check if this works correctly and doesn't leave warnings in the browser console. I think it will, but if not, I guess we should add the new .ftl in browser.xhtml after all.

To test this, simply load any page and click the star button in the address bar (or hit the shortcut - cmd-D on mac, ctrl-D on Windows).
