On distro builds on Linux, there is no update manager, so I see:
```
Cc[aContract] is undefined XPCOMUtils.jsm:144
XPCU_serviceLambda resource://gre/modules/XPCOMUtils.jsm:144
get resource://gre/modules/XPCOMUtils.jsm:58
lastBrowserUpdateDate resource:///modules/UrlbarProviderSearchTips.jsm:496
_maybeShowTipForUrl resource:///modules/UrlbarProviderSearchTips.jsm:361
InterpretGeneratorResume self-hosted:1468
AsyncFunctionNext self-hosted:674
```
on release. AFAICT this code is all still there on nightly.
It should probably check `MOZ_UPDATER` or something.
