Status: VERIFIED FIXED

(Toolkit :: Printing, defect, P1)

Description

Attachment: blank.gif

Affected versions

• 82.0a1 (BuildId:20200825154412)
• 81.0b2 (BuildId:20200825191644)

Affected platforms

• Ubuntu 20.04 64bit
• Windows 10 64bit
• macOS 10.14

Steps to reproduce

1. Launch Firefox.
2. Access the following link.
3. Hit CTRL + P.
4. Reach the Orientation section via keyboard navigation (to easily reproduce this).
5. Use your arrow keys to fastly switch between Portrait & Landscape orientations.

Expected result

• The print preview successfully updates each time successfully displaying the pdf document that is about to get printed.

Actual result

• After several switches, the print preview displays a blank document (sometimes not all the pages are displayed as blank but some are).

Regression Window

• I don’t think that this is a regression.

Additional Information

• For further information regarding this issue please observe the attached screencast.
• Physical printer is connected but it seems that it won’t print (it displays “processing” but it seems that the print job is automatically canceled).
• Save to pdf outputs a blank document.
• Also, I've noted that the same issue occurs if fastly changing between the available destinations with, sometimes, even a difference (the print preview displays an infinite loading animation & my memory usage increases greatly when this is reproduced). I will continue investigating this behavior.

I can't reproduce this on Windows or my Ubuntu VM with a more recent Nightly. I downloaded the release you listed and immediately reproduced on Windows. Do you mind checking if this is still reproducible?

Bug 1636728 probably fixed this. (It's not on Beta yet.)

Comment 3

[Emil Ghitta, QA [:emilghitta]]

This is no longer reproducible on latest Nightly.

This is verified fixed using Firefox 82.0a1 (BuildId:20200827212940) on Windows 10 64bit, macOS 10.14 & Ubuntu 18.04 64bit.

Leaving the ni? as a reminder to verify this once Bug 1636728 gets uplifted in beta.
