We have the opportunity to release a new feature in Firefox, a self-auditing system giving advanced users useful information and tips about the performance of their browser. These users can also share this data with Mozilla so as to help improve Firefox performance. This new feature takes the form of a new in-product page accessible at about:healthreport The product part of it are a few strings in the Firefox source code, the server-side part is a lang file to translate the UI, explain what the collected values are and give performance tips. The repository for your locale is: https://svn.mozilla.org/projects/l10n-misc/trunk/firefoxhealthreport/locale/mn/ The specific file to translate is: https://svn.mozilla.org/projects/l10n-misc/trunk/firefoxhealthreport/locale/mn/fhr.lang There is a staging server being set up there: http://fhr-dev.allizom.org/mn/ (Note at the time of filing this bug, the staging server is not autoupdating code and translations yet and is in heavy works since localizers are working in parallel to the webdev team creating this mini-site). We might release this feature for the next Aurora but that's totally unsure, given that this is server side, we should be able to update the server after we have released the next Firefox Aurora. Thanks
Since you seem to already be translating Firefox on Pootle http://mozilla.locamotion.org/projects/firefox/ you might want to translate the Firefox Health Report files there also. We've setup an FHR project on Pootle: http://mozilla.locamotion.org/projects/fhr/ If your language is not enabled then just ask and we'll enable it. If you are an existing Pootle translator for your language then you should simply be able to translate on the project with your normal rights. If you aren't translating on Pootle then sorry for the noise or any confusion.
Wontfix, we dropped this locale on the product side
