Hi,

I know this is a common issue for many sandboxed applications.
I've got that with Slack, which was unable to open any external URLs. Also it was impossible to sign-in into new workspace when running in the jail.

I had slow disk, so I tried to take advantage of having ~/.cache directory on temporary file system to reduce disk writes.
And profile option private-cache comes in handy.
After adding it to slack.profile I've got external links being opened in default desktop browser, to my surprise. I haven't tested the sign-in process.

Not sure how those things are connected, though.
I think we could add it as the default into the profile, because it does no harm and even improves isolation a little bit. The only drawback I observed is slightly increased start-up time for Slack. But that should not be an issue on relatively modern hardware.
