I landed a fix for bug 1195930 ( Use origin in QuotaManager) today, it's now on 
m-c.

We had to do backwards-incompatible changes under <profile>/storage directory, 
so once a profile is used with newest nigthly, then any storage API
controlled by Quota Manager (IndexedDB, DOM cache, asmjs cache) won't work in 
older builds.

We didn't have a versioning schema for <profile>/storage before this bug, so 
the incompatibility is signaled by this nonsensical warning in older
builds:

WARNING: Unknown file found!: file 
/Users/joe/Sources/Mozilla/dom/quota/ActorsParent.cpp, line 3541

I assume there are plans to warn users about this kind of issue. Just printing 
something to the terminal isn't really useful.
yeah, bug 1246615

Could we clean up the data if the FF version user is using can't handle it?
hm, clean up indexedDB databases, etc. ?

yes, wipe out data so that user gets a browser which works. Perhaps warn/ask 
user before doing it?
