No. Crowdin API integration with our source tree simply isn't feasible at the moment. it would take considerable time and work to set that up, in addition to the problem that it's not set up to use different languages except through language packs.
Potentially, you could build language packs yourself and check the result that way, from the https://repo.palemoon.org/MoonchildProd ... calization repo.
