Hi,
https://bugzilla.mozilla.org/show_bug.cgi?id=1215694 landed, moving the
pocket files, and a few strings within.
You want to start with
hg mv browser/chrome/browser/browser-pocket.properties
browser/extensions/pocket/pocket.properties
There are more strings to add to that, they're coming from
browser.dtd:
pocketMenuitem.label
saveLinkToPocketCmd.accesskey
saveLinkToPocketCmd.label
saveToPocketCmd.accesskey
saveToPocketCmd.label
customizableui/customizableWidgets.properties:
pocket-button.label
pocket-button.tooltiptext
