I've been updating our Iris automation for updating the browser then checking the default search engine. I discovered that with build older than Fx66, update causes the default search engine to be set to Google, when prior to the update the search engine is correctly set to Baidu. This seem similar to bug 1565315. Use the same steps to reproduce, except start with a zh-CN build with browser.search.region = 'CN'
