Backporting

Timeline

  • Immediate: patchset needed as soon as possible
  • Next Minor Stable Release: patchset that needs to be verified in nightly before backport
  • Eventually: patchset that needs to be verified in alpha before backport
  • No Backport (preferred): patchset for the next major stable

(Optional) Justification

  • Emergency security update: patchset fixes CVEs, 0-days, etc
  • Censorship event: patchset enables censorship circumvention
  • Critical bug-fix: patchset fixes a bug in core-functionality
  • Consistency: patchset which would make development easier if it were in both the alpha and release branches; developer tools, build system changes, etc
  • Sponsor required: patchset required for sponsor
  • Other: please explain

Merging

  • Merge to tor-browser - !fixups to tor-browser-specific commits, new features, security backports
  • Merge to base-browser - !fixups to base-browser-specific commits, new features to be shared with mullvad-browser, and security backports
    • NOTE: if your changeset includes patches to both base-browser and tor-browser please clearly label in the change description which commits should be cherry-picked to base-browser after merging

Change Description

The patch for browser-context.inc disables the HTML Format and text/html types and the patch for nsCopySupport.cpp disables the application/x-moz-file-promise-url type which contain the source url when an image is copied to the clipboard.

Disabling the promise additionally stops the image from being downloaded into the temp folder of the OS when copying an image.
