You can line them up next to each other -- life is good now

Confirm your changes in details view - you need to refresh the page with details to up date it
For the next record you want to edit switch back to the list view. Right click on the next record you wish to edit and open in a new tab.
Copy the record ID of that record to the URL of the details tab. That will open up the details view to the next record so you don't have to do the duplicate tab dance again
