Attachment: video showing the issue

Found in

• 133.0a1 (2024-10-24)

Affected versions

• 133.0a1

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-1.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
• Have a folder that contains at least 15 files (file format is not important)

Tested platforms

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

Steps to reproduce

1. Go to https://developer.mozilla.org/en-US/docs/Web/API/HTMLInputElement/webkitdirectory
2. Upload the folder from prerequisite by either pressing the “Browse” button and selecting the folder or by dragging and dropping the folder onto the “Browse” button from the Examples section
3. Observe the “Scan in progress” dialog for each scanned file

Expected result

• “Scan in progress” dialog should appear and disappear for each scanned file, without stacking

Actual result

• “Scan in progress” dialogs are stacked on top of each other, creating a shadow effect

Regression range

• Mozzregression points to bug 1915351. Before this, only the first file was scanned

Additional notes

• See the attached video
• Not reproducing when uploading multiple files (without the folder)

:gstoll, since you are the author of the regressor, bug 1915351, could you take a look? Also, could you set the severity field?

I'm going to leave this blocking the metabug for now since I'd like to understand why this is different in the folder case versus just uploading multiple files.

Setting Fx133 to fixed since the regressor was backed out

Making this bug not block bug 1882607, but :handyman will file a new bug so that canceling one of the files will cancel the whole operation.

Hi @greg,
While using Firefox Nightly 137.0a1 (2025-02-16) on Windows 11, I noticed that when multiple files are scanned (e.g. shouldAllow.txt and shouldBlock123456789.txt files), the bottom part of the dialog for the next scanned file becomes visible beneath the current one, in addition to the shadow effect. This seems to happen due to the longer file name of the next file (please see the attached screenshot). Could this be related to bug 1936227?
Should I file a new ticket for this, or is it okay to track it here? Thanks in advance!
