:robwu, since you are the author of the regressor, bug 1810753, could you take a look?

Comment 2

[Rob Wu [:robwu]]

While bug 1810753 introduced the test for extra coverage, the implementation changes is not the cause of the failure.

It is unfortunately a known issue: on Windows, attempting to remove a download after it was downloaded does not always work because the file is locked. In the test I already referenced bug 1654819 as a potential cause of another potential intermittent failure.

To help with tracking this class of bugs more accurately, I'm going to file a new bug that is a dependency of this bug and other bugs related to this.

FYI, the relevant part of the log is:

(xpcshell/head.js) | test test_download_api_ignores_dnr_from_other_extension pending (2)
