One more note: I've just noticed that this landed too
https://hg.mozilla.org/releases/mozilla-aurora/rev/d560a3e332dd
It's an accesskey change for English. This won't have any consequence to
locales working on Pontoon or Mercurial, but I've discovered that Pootle
removes both the string and the accesskey (marking them as fuzzy).
You'll need to go in and confirm the existing string, maybe double check if
you had a conflicting accesskey in your localization.
