I just tried to simulate the problem with newer/older firefox, but with
given code snippet I get an error event instead of "undefined"
It's probably something else ...

Can you have the user try in a fresh profile?
I think this behavior might occur if they used a profile in a newer version
of firefox (like nightly 57) and then try to take it back to an older
version (like release 55). Database schemas can be updated in various
storage APIs on disk which prevent older versions of firefox from opening
the any storage for the origin.

I'm trying to help some users of my extension with a problem.
Unfortunately I can only offer suggestions of things to try and then wait
for a reply.
I asked one to put this code in the web console and tell me what happened:
try {
var request = indexedDB.open('thisIsATest', 1);
request.onsuccess = console.log;
request.onerror = console.error;
request.onblocked = console.error;
request.onupgradeneeded = console.log;
'finished';
} catch(ex) {
console.error(ex);
}
What you'd expect to see on the console is either "finished" and then one
or more messages from the event handlers, or an error from the catch block.
What they got instead was: undefined.
This surely must mean that indexedDB.open is failing but not throwing an
exception. I've tried disabling indexedDB, or making the appropriate
directory read-only, but in both cases an error is reported (even if it is,
helpfully, "UnknownError").
So I'm stuck. What could be causing this, and what can I do about it?
