Ubuntu closes popup on file prompt

[chucklam]

Problem:

I want to import a wallet in the Send-TX tab. This is what I initially see when I have the extension opened.

When I click on the 'SELECT WALLET FILE' button, a file dialog shows up, but the extension popup goes away.

Selecting a file doesn't do anything. I believe it's because Chrome has closed the extension app already so there's nothing for the call to return to.

This is a bug with Ubuntu Chrome. This affects MetaMask too, and right now they use a hack around it.
MetaMask/metamask-extension#1136

Versions:

• Ubuntu 16.04
• Chrome Version 66.0.3359.181 (Official Build) (64-bit)
• WebExtensionWallet 0.1.0

Thanks for your feedback. We have noticed this problem before, and there is a tricky solution #4

I'll try to detect system info, and if it's Ubuntu, then extension will pop up a new tab for user to import their wallet file.
