Commits: 8e51811f by Ray Kraesig at 2025-03-31T22:42:56+02:00 Bug 1950056 - extend use of FOS_NODEREFERENCELINKS r=Gijs,win-reviewers,gstoll
In the modern era of user-customizable Quick Access sidebars on every file dialog, navigating via `.lnk` files is rather less useful than it was twenty years ago.
Disable link-following in file-open dialogs by default, to prevent any of the usual security issues involving symlink smuggling. Allow overriding this behavior via a pref, for users who don't care.
(File-save dialogs have a more nuanced guard against that sort of thing; this patch doesn't affect that.)
