[tor-browser/tor-browser-78.9.0esr-10.5-1] Bug 19273: Avoid JavaScript patching of the external app helper dialog.
by sysrqb＠torproject.org 17 Mar '21

commit 1569ceb34f2c6e14c993a25ba0e5055647aadd3a Author: Kathy Brade <brade(a)pearlcrescent.com> Date: Tue Jun 28 15:13:05 2016 -0400 Bug 19273: Avoid JavaScript patching of the external app helper dialog. When handling an external URI or downloading a file, invoke Torbutton's external app blocker component (which will present a download warning dialog unless the user has checked the "Automatically download files from now on" box). For e10s compatibility, avoid using a modal dialog and instead use a callback interface (nsIHelperAppWarningLauncher) to allow Torbutton to indicate the user's desire to cancel or continue each request. Other bugs fixed: Bug 21766: Crash with e10s enabled while trying to download a file Bug 21886: Download is stalled in non-e10s mode Bug 22471: Downloading files via the PDF viewer download button is broken Bug 22472: Fix FTP downloads when external helper app dialog is shown Bug 22610: Avoid crashes when canceling external helper app downloads Bug 22618: Downloading pdf file via file:/// is stalling --- .../exthandler/nsExternalHelperAppService.cpp | 202 +++++++++++++++++---- uriloader/exthandler/nsExternalHelperAppService.h | 3 + .../exthandler/nsIExternalHelperAppService.idl | 47 +++++ 3 files changed, 217 insertions(+), 35 deletions(-) diff --git a/uriloader/exthandler/nsExternalHelperAppService.cpp b/uriloader/exthandler/nsExternalHelperAppService.cpp index 4ff7ed2e27cc..0dcc1d3ed6ab 100644 --- a/uriloader/exthandler/nsExternalHelperAppService.cpp +++ b/uriloader/exthandler/nsExternalHelperAppService.cpp @@ -132,6 +132,9 @@ static const char NEVER_ASK_FOR_SAVE_TO_DISK_PREF[] = static const char NEVER_ASK_FOR_OPEN_FILE_PREF[] = "browser.helperApps.neverAsk.openFile";
