infinispinnering after a Firefox crash

[uhoreg]

Firefox crashed earlier today, and now, when I try to load /staging or /develop, I get an infinispinner and it never loads. Here's the contents of the console:

I'm guessing that the bad serialized structured data (truncated) indexeddb-worker.js:4025:18 is not something that should be happening, and I guess it means that Firefox decided to take out part of my IndexedDB with it when it crashed. There probably isn't much that can be done with a borked IndexedDB, but it should probably do something more useful than infinispinnering.

Also, looking at the Network tab of the developer tools, it doesn't seem to be making any /sync requests.

Closing as ancient and very little chance we can repro.. unless @uhoreg is still unable to login..? :)
