I used this extension for quite some time, and it works great... but then I noticed its permissions. It requires permission to "Access your data for all websites." It also requires permission to "Read and modify bookmarks." There's no reason those permissions are needed for this capability, and I find it very concerning to say the least. There's a similar extension ("Snooze tabs" instead of "Snooze Tabs") that doesn't require either permission. I've switched to that one and recommend others do the same, at least until this extension removes the permissions to access your private data.
