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
  • Localization: typos and other localization changes that should be also in the release branch
  • Other: usability, see the description

Change Description

From the upstream bug, it seems that Android 14 on Samsung devices removed the font Firefox used, so it falls back to a font that has a very bad readability for Korean users.

This will change fingerprint for those users, but we don't customize the font list on Android for now, so it might be fine to just take it.

It's a usability improvement, it might sense to Backport. But we haven't had any requests so far, so it might also make sense to just wait.

How Tested

Not tested, but upstream fix that adds an item to the preferences, without removing anything, it seems safe to take.
