Firefox iOS v12: strings in Pontoon

Hi localizers,

Heads-up that I've just exposed strings on Pontoon for Firefox iOS v12
<https://pontoon.mozilla.org/projects/firefox-for-ios/>. There is a total
of 32 new strings.

Targeted deadline for localizing and testing is May 23 (so that I can
update the list of shipping locales by the next day). As usual, let me know
if your team has any concern so we can try to adapt accordingly.

Screenshots will be updated twice a week, on Tues and Fridays.

thanks!
