Comment 1 for bug 1395273

Thanks for your report.

Previously firefox-locale-XX was a "recommend" in the language-pack-XX-base packages. That recommend was dropped last year, and as regards 14.04 it happened via an update after the initial release. This ought to explain why the firefox translations disappeared after an update. (You probably run "sudo apt-get autoremove".) So it was a one-off incident.

The coverage of the Scottish Gaelic translations in firefox is an upstream matter, and thus not an Ubuntu bug. I see that you are a member of the Scottish Gaelic translation team in Ubuntu, so you may want to get involved in the translation of firefox as well.

Closing this bug.
