commit 12847934f5c7baf4e94945ec433f1b2fdcf33625 Author: Richard Pospesel <richard@torproject.org> Date: Fri Apr 20 16:03:41 2018 -0700 Bug 25458: UI customization half-broken in Tor Browser 8.0a3 Fixed fallout from #25147. Some of the functionality of the UI Customize screen is dependent on setting innerHTML on divs. Since the code runs in the System context, the HTML was being sanitized and broke page functionality. The offending statements have been switched to the unsafeSetInnerHTML() method which bypasses sanitization in System context. --- browser/components/customizableui/CustomizeMode.jsm | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/browser/components/customizableui/CustomizeMode.jsm b/browser/components/customizableui/CustomizeMode.jsm index 49868cdbd4a0..4c32fd867c09 100644 --- a/browser/components/customizableui/CustomizeMode.jsm +++ b/browser/components/customizableui/CustomizeMode.jsm @@ -690,13 +690,13 @@ CustomizeMode.prototype = { // Put the tip contents in the popup. let bundle = this.document.getElementById("bundle_browser"); const kLabelClass = "customization-tipPanel-link"; - messageNode.innerHTML = bundle.getFormattedString("customizeTips.tip0", [ + messageNode.unsafeSetInnerHTML(bundle.getFormattedString("customizeTips.tip0", [ "<label class=\"customization-tipPanel-em\" value=\"" + bundle.getString("customizeTips.tip0.hint") + "\"/>", this.document.getElementById("bundle_brand").getString("brandShortName"), "<label class=\"" + kLabelClass + " text-link\" value=\"" + bundle.getString("customizeTips.tip0.learnMore") + "\"/>" - ]); + ])); messageNode.querySelector("." + kLabelClass).addEventListener("click", () => { let url = Services.urlFormatter.formatURLPref("browser.customizemode.tip0.learnMoreUrl");
