Error Opening 3Box Space: "OpenError: A mutation operation was attempted on a database that did not allow mutations"

[polluterofminds]

Describe the bug
I created a space in one browser, then I logged in using another browser and tried to access that space. I got the following error:

"OpenError: A mutation operation was attempted on a database that did not allow mutations"

It's worth noting that the space.syncDone promise never resolves. @oed said this might be a bug, but I haven't had a chance to open its own dedicated issue.

Another note: this could be caused by trying to access a space from a private browser, maybe?

To Reproduce
Steps to reproduce the behavior:

1. Open Box with Ethereum account
2. Open space
3. Store some data to said space
4. Use a private browser and Open Box with same Ethereum account.
5. Try to open the same space, error should be thrown.

Expected behavior
A user should be able to sign in and access a space from any browser or device.

Desktop (please complete the following information):

• OS: [e.g. iOS]: MacOS 10.14.6
• Browser [e.g. chrome, safari] Firefox 69.0.1

Hey @jehunter5811 thanks for reporting! Can you provide some more information? In particular I'm wondering what wallet your are using. Is this using MetaMask in firefox or something different?

[polluterofminds]

Sorry for the delay in getting back to you @oed. I'm using a custom, custodial wallet (SimpleID). Do you think that's the problem?

[oed]

@jehunter5811 it shouldn't be a problem as long as it conforms to the standard ethereum rpc-provider api.
It could have something to do with permissions in the private tab and localstorage/indexedDB perhaps though.

Seeing this issue too on Firefox when calling Box.openBox(). Brave with shields enabled doesn't seem to work either so it might be a cross-site storage issue.
