The default behaviour of sharing tab history is clearly a glaring oversight of the team. Intentionally infringing on privacy or not, the feature is obviously a privacy issue that needs to be addressed.

@dev-team,
1. can users who've perhaps unwittingly shared their tab history delete them if they lose access to the computer that they used to create them?
2. can users easily see a list of all the tab lists they've shared?
3. do the shared links ever expire? Is there a default expiry?
