[tor-commits] [tor-browser/tor-browser-86.0-10.5-2] Bug 4234: Use the Firefox Update Process for Tor Browser.
commit e2cb1b58b797aa5917cd820ee93fab2701c32906
Author: Kathy Brade <brade@xxxxxxxxxxxxxxxxx>
Date: Fri Jan 13 11:40:24 2017 -0500
Bug 4234: Use the Firefox Update Process for Tor Browser.
The following files are never updated:
TorBrowser/Data/Browser/profiles.ini
TorBrowser/Data/Browser/profile.default/bookmarks.html
TorBrowser/Data/Tor/torrc
Mac OS: Store update metadata under TorBrowser/UpdateInfo.
Removed the %OS_VERSION% component from the update URL (13047) and
added support for minSupportedOSVersion, an attribute of the
<update> element that may be used to trigger Firefox's
"unsupported platform" behavior.
Hide the "What's new" links (set app.releaseNotesURL value to about:blank).
Windows: disable "runas" code path in updater (15201).
Windows: avoid writing to the registry (16236).
Also includes fixes for tickets 13047, 13301, 13356, 13594, 15406,
16014, 16909, 24476, and 25909.
Also fix Bug 26049: reduce the delay before the update prompt is displayed.
Instead of Firefox's 2 days, we use 1 hour (after which time the update
doorhanger will be displayed).
Also fix bug 27221: purge the startup cache if the Tor Browser
version changed (even if the Firefox version and build ID did
not change), e.g., after a minor Tor Browser update.
Also fix 32616: Disable GetSecureOutputDirectoryPath() functionality.
Bug 26048: potentially confusing "restart to update" message
Within the update doorhanger, remove the misleading message that mentions
that windows will be restored after an update is applied, and replace the
"Restart and Restore" button label with an existing
"Restart to update Tor Browser" string.
Bug 28885: notify users that update is downloading
Add a "Downloading Tor Browser update" item which appears in the
hamburger (app) menu while the update service is downloading a MAR
file. Before this change, the browser did not indicate to the user
that an update was in progress, which is especially confusing in
Tor Browser because downloads often take some time. If the user
clicks on the new menu item, the about dialog is opened to allow
the user to see download progress.
As part of this fix, the update service was changed to always show
update-related messages in the hamburger menu, even if the update
was started in the foreground via the about dialog or via the
"Check for Tor Browser Update" toolbar menu item. This change is
consistent with the Tor Browser goal of making sure users are
informed about the update process.
Removed #28885 parts of this patch which have been uplifted to Firefox.
