Comment 2

[Jonathan Kew [:jfkthame]]

AFAICS, it wouldn't be possible for web content to do this, because the printPreview() method isn't web-exposed.

@jwatt, do you think we should be concerned about this, or is it just an expected result of misusing a chrome-only API?

[BugBot [:suhaib / :marco/ :calixte]]

:jwatt, since this bug contains a bisection range, could you fill (if possible) the regressed_by field?
For more information, please visit auto_nag documentation.

Comment 5

[Jonathan Watt [:jwatt]]

I'll revisit this after fixing bug 1747851 since the fix for that may fix this also.

Comment 6

[BugBot [:suhaib / :marco/ :calixte]]

Set release status flags based on info from the regressing bug 1745452

Comment 7

[BugBot [:suhaib / :marco/ :calixte]]

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

For more information, please visit auto_nag documentation.

Comment 8

[Hiroyuki Ikezoe (:hiro)]

S3 since the API triggers this crash, printPreview() isn't available on the Web.

Comment 9

[Daniel Holbert [:dholbert]]

(In reply to Jonathan Watt [:jwatt] from comment #5)

I'll revisit this after fixing bug 1747851 since the fix for that may fix this also.

Ticking ni=you as a reminder. :)

[Bugmon [:jkratzer for issues]]

Bugmon was unable reproduce this issue.
Removing bugmon keyword as no further action possible. Please review the bug and re-add the keyword for further analysis.

Comment 11

[Jason Kratzer [:jkratzer]]

A change to the Taskcluster build definitions over the weekend caused Bugmon to fail when reproducing issues. This issue has been corrected. Re-enabling bugmon.
