commit c4e69d166471ffd1acf8ddf1c7e509b50e2a249f Author: Alex Catarineu acat@torproject.org Date: Fri Sep 4 12:34:35 2020 +0200
Bug 40091: Load HTTPS Everywhere as a builtin addon in desktop
This loads HTTPS Everywhere as a builtin addon from a hardcoded resource:// URI in desktop. It also ensures that the non-builtin HTTPS Everywhere addon is always uninstalled on browser startup.
The reason of making this desktop-only is that there are some issues when installing a builtin extension from geckoview side, making the extension not available on first startup. So, at least for now we handle the Fenix case separately. See #40118 for a followup for investigating these. --- browser/components/BrowserGlue.jsm | 37 ++++++++++++++++++++++ .../mozapps/extensions/internal/XPIProvider.jsm | 13 ++++++++ 2 files changed, 50 insertions(+)
