Search in Private Browsing New Tab impact study

Firefox Release 66

We have finished testing the Search in Private Browsing New Tab impact study experiment.

QA’s recommendation: GREEN - SHIP IT

Reasoning:

  • No new issues have been found during testing.

  • A single known issue has been encountered during testing, Bug 1530706, which is an intermittent issue only on Mac using a Japanese keyboard. We do not consider this issue damaging enough to block the experiment, but we would recommend fixing it as soon as possible.

  • Windows 10

  • Mac 10.14

  • Arch Linux 4.14
