1869868 - Do not consult DLP when pasting items from the same origin

Status: RESOLVED FIXED

(Firefox :: Data Loss Prevention, task)

Description

[David Parks [:handyman]]

Similar to the async clipboard work in bug 1777448, we want to avoid checking with with data-loss prevention software when copy-pasting/drag-dropping contents of a page from one spot to another that does not change the origin. The work in that bug should ease this for clipboard operations. For drag-and-drop, Firefox already has mozSourceNode, that holds the element that was the source of the drag (if any).

Something like this is done with the clipboard cache in nsBaseClipboard::AsyncGetData(). This checks that the origin is the same, but not that it comes from the same tab.

I'm working on the clipboard case.

For easy reference, the pref name I'm adding is "browser.contentanalysis.bypass_for_same_tab_operations"

Now that the clipboard part is in, unassigning this from myself.

Bug 1902110 covers the drag and drop side of this, so changing this to just cover the clipboard part and closing it.
