Bug 1428165 - Part 2: Fix history expiration query. r=nalexander, a=gchang 'modified' value might be missing; in SQLite, max(123, null) is null, and so we must coalesce fields which might be missing values. MozReview-Commit-ID: Bn1P0kdaHHT

Bug 1428165 - Part 1: Ensure that 'modified' and 'created' timestamps are set when inserting history from sync. r=nalexander, a=gchang This fixes a regression introduced in Bug 1291821. History records would be bulk-inserted from sync, and our ContentProvider would erroneously forget to set these two timestamp fields. MozReview-Commit-ID: 2k0afijN62H

Bug 1246883 - Load UA Stylesheet when printing the SVG document. r=jwatt, a=gchang Currently, Gecko load only minimal-xul.css if the document is the SVG[1]. In the case of printing SVG document, gecko should load ua.css for using style which related to print. This patch will load ua.css when printing the SVG document.

Bug 1403365 - Fix intermittent in browser_pageinfo_firstPartyIsolation.js. r=baku, a=test-only When we try to load https://example.com/browser/browser/base/content/test/pageinfo/image.html, sometimes BrowserTestUtils will return early even the page doesn't load yet, for example, the browser.currentURI is still about:blank. And loading about:blank will cause error in pageInfo.js, hence caused the timeout. So I add more parameters to browserLoaded to make sure browwserLoaded is returned with the correct url.

Bug 1403923 - Safely shutdown Firefox from in delete_session. r=jgraham, a=test-only With the request to shutdown the browser, a given amount of time has to be waited to allow the process to shutdown itself. Only if the process is still running afterward it has to be killed. Firefox has an integrated background monitor which observes long running threads during shutdown, and kills those after 65s. To allow Firefox to shutdown on its own, geckodriver has to wait that time, and some additional seconds. MozReview-Commit-ID: 4LRLQE0jZzw
