We just upgraded from 5.0 FP14 to 5.1 FP12. When users action an item and the form closes the browser tab, they are now getting an IE window popup that says "The webpage you are viewing is trying to close the tab. Do you want to close this tab?". I never received this message when closing the brower windows through code in prior version of K2. Only happens in IE 11 but not in Chrome. Any thoughts how to solve this issue?

Check that the URL for the tab you are trying to close does not end in "?"

It has got something to do with your IE security settings. Please read the following blog posts for the same.
Please try to do following and see if that helps.
I created a ticket for K2 and this is what they said:
The 'Close the browser window' rule has a small flaw, HTML 5 standards dictate that windows that have not been opened by a script cannot be closed by that script: https://www.w3.org/TR/html51/browsers.html#dom-window-close
Here's a community post regarding this issue: http://community.k2.com/t5/K2-blackpearl/Rule-quot-close-the-browser-window-quot-with-different-results/m-p/63350#M17734
This label for the rule does cause confusion and we currently have a feature request to change it to 'Close the Form'.
We also have a workaround:
Create a Literal, Hidden Data Label on your form, and when you wish to close the window, create a Transfer Data rule that transfers the following script into the Data Label:
<script>window.open('', '_self', ''); window.close();</script>
This script opens a blank window on the current page and then closes it, getting around the aforementioned issue.
