commit 8a1081b4c6d0fd1a6350c9fae8f7acb310bb5414 Author: Alex Catarineu acat@torproject.org Date: Mon Sep 9 13:04:34 2019 +0200

Bug 31575: Replace Firefox Home (newtab) with about:tor

Avoid loading AboutNewTab in BrowserGlue.jsm in order to avoid several network requests that we do not need. Besides, about:newtab will now point to about:blank or about:tor (depending on browser.newtabpage.enabled) and about:home will point to about:tor. --- browser/components/BrowserGlue.jsm | 33 ++---------------------- browser/components/newtab/AboutNewTabService.jsm | 15 +---------- browser/components/preferences/home.inc.xhtml | 4 +-- browser/components/preferences/preferences.xhtml | 5 +++- browser/modules/HomePage.jsm | 2 +- 5 files changed, 10 insertions(+), 49 deletions(-)
