The severity field is not set for this bug.
:royang, could you have a look please?

Comment 2

[Roger Yang [:royang]]

From stack, it looks like it's related to opening input stream in PDF. Moving to GV.

Comment 3

[Olivia Hall [:olivia]]

Thanks for reporting! A few questions could help us debug:

• What model is your device?
• Does this happen on all pages or only certain pages?
• Does it seem like it happens only if you tap through very quickly?

The error is happening in the GeckoViewPrintDocumentAdapter. It seems like a race condition could be at play here. (Content is generated into a PDF file before printing.)

Comment 4

Thank you for your insightful analysis! I have followed your suggestion, tried to produce the bug, and finally succeed.

The bug will appear when: you click share->print and then click back soon as the previewing is not finished.

Model: Google Plxel 2

Pages: I have tried several pages with the bug successfully reproduced. For example, the "Firefox for Android Support" Page, the "pocket app" page

Situation: Click back when previewing will lead to the bug, but after the preview is finished then click back, the bug won't happen

[Vasilica Tamas QA [:vtamas]]

I was not able to reproduce this issue following the steps from Comment 4 on Firefox Nighty 137 (2025-03-03) using a Google Pixel 8 (Android 15) and a Samsung S24 Ultra (Android 14).

Could you please attach a video with the issue?
Thanks!
