So the main problem here is that as things stand synchronously loading ftl files from langpacks fail. Synchronous loads use [`Cu.readUTF8URI`](https://searchfox.org/mozilla- central/rev/05a22d864814cb1e4352faa4004e1f975c7d2eb9/intl/l10n/L10nRegistry.jsm#754) which underneath uses the `URLPreloader` which [only supports file or omnijar urls](https://searchfox.org/mozilla- central/rev/05a22d864814cb1e4352faa4004e1f975c7d2eb9/js/xpconnect/loader/URLPreloader.cpp#565). So attempting to load strings for browser.xhtml which uses synchronous localization fails for the langpack and so falls back to the built-in localization (yay for fallback!).
Unfortunately we cache these load failures which effectively poison the langpack for future localization passes. In particular we cache the fact that `branding/brand.ftl` isn't available in the langpack and then any attempt to generate bundles that include `branding/brand.ftl` as a resource (which the majority of pages do) fail because that file is cached as missing. That seems like a different bug, I had the impression that fluent would fall back on a per-resource level, not ignore the entire locale if just one resource is missing, but we don't need to solve that to fix this. There are a couple of ways to solve this. Probably the ideal solution would be to make the `URLPreloader` support loading out of langpacks. But for a safer patch for beta I've just made `loadSync` fallback to an alternative method of loading the ftl file in the event that `Cu.readUTF8URI` fails. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1846371 Title: firefox 70.0 beta 11 isn't fully translated Status in Mozilla Firefox: Confirmed Status in firefox package in Ubuntu: Triaged Bug description: (this was initially spotted by ricotz) I'm running firefox 70.0~b11+build1-0ubuntu0.19.10.1 from ppa:mozillateam/firefox-next with a French locale, and the UI is not fully translated to French.
