Affected versions

• 132.0a1 (2024-09-23)

Tested platforms

• Affected platforms: Windows 11, Windows 10
• Unaffected platforms:macOS 12, Ubuntu

Preconditions

• Download the DLP test assets from https://drive.google.com/file/d/1yjqVRuxdKV3WnO7D2wzMgDXBuYBxUgVw/view
• Create a distribution folder inside the Firefox folder and paste the policies-2.json to it and then rename it to policies.json
• run the DLP agent in CMD using: .\content_analysis_sdk_agent.exe --user --toblock=.\d{3}-?\d{2}-?\d{4}. --towarn=.warn. --delays=10

Steps to reproduce

1. Open two Firefox windows.
2. In one window open https://www.wikipedia.org/ and in other window this link
3. Drop text from the pocket window to the text area inside Wikipedia on another window two times consecutively..

Expected result

• No tab crash.

Actual result

• Tab crashes.

Regression range

• This happens after drag and drop scanning was introduced inside Content Analysis (bug 1910452).

Additional notes

• Attached a screen recording.
• Note: sometimes the tab crash does not happen immediately, it happens only after some time.
• Crash signature: https://crash-stats.mozilla.org/report/index/a6ca96a9-9fae-4534-a80b-94c840240924#tab-details. It seems that has the same signature as bug 1918579.

Hopefully being fixed by bug 1915351.

I verified that bug 1915351 fixes this. My guess is that since the dialog goes away too soon the first drag session is in progress when we drag for the second time, and that makes bad things happen, so I'm going to mark this as a duplicate of bug 1917334.

Thank you, Greg! Confirming that this issue can no longer be reproduced with Firefox 133.0a1 (2024-10-24) after bug 1915351 was landed.
