-    hints that we could re-test this once we have GTK 3.24.42 (with the
-    now-current gtk3-3.24.41 the original problem is still reproducable,
-    but toggling this flag does fix it for me)

+## Cursors
+
+From Firefox 140.2 on, this port defaults to using the new (themed)
+cursor selection. On the upside, this makes Firefox respect the
+desktop environment's theme, on the downside this breaks compatibility
+with the legacy X cursor names. If you experience issues (i.e. the
+mouse cursor not changing to the pointer ("hand") when hovering over
+links), your desktop environment is most likely still set to the legacy
+default/builtin "theme". To remedy this, either
+- set about:config variable "widget.gtk.legacy-cursors.enabled" to "true"
+  to re-enable the legacy cursors, or
+- use the Xcursor framework to set a cursor theme (e.g. X resource
+  item Xcursor.theme), see Xcursor(3) for details. The Adwaita theme
+  will have been installed as a dependency of gtk3 and does work.
+The latter option is only available for X environments.
+
 ## Audio backend
 
 Currently used audio backend can be inspected on `about:support` page.

-commit 46a89fb0319d673b3139a068e3d89aed9f44fc16
-Author: Christoph Moench-Tegeder <cmt@burggraben.net>
-
-    use gdk legacy cursor interface by default
-    
-    Upstream https://bugzilla.mozilla.org/show_bug.cgi?id=1876366#c16
-    hints that we could re-test this once we have GTK 3.24.42 (with the
-    now-current gtk3-3.24.41 the original problem is still reproducable,
-    but toggling this flag does fix it for me)

+## Cursors
+
+From Firefox 142 on, this port defaults to using the new (themed)
+cursor selection. On the upside, this makes Firefox respect the
+desktop environment's theme, on the downside this breaks compatibility
+with the legacy X cursor names. If you experience issues (i.e. the
+mouse cursor not changing to the pointer ("hand") when hovering over
+links), your desktop environment is most likely still set to the legacy
+default/builtin "theme". To remedy this, either
+- set about:config variable "widget.gtk.legacy-cursors.enabled" to "true"
+  to re-enable the legacy cursors, or
+- use the Xcursor framework to set a cursor theme (e.g. X resource
+  item Xcursor.theme), see Xcursor(3) for details. The Adwaita theme
+  will have been installed as a dependency of gtk3 and does work.
+The latter option is only available for X environments.
+
 ## Audio backend
 
 Currently used audio backend can be inspected on `about:support` page.

-Author: Christoph Moench-Tegeder <cmt@burggraben.net>
-
-    use gdk legacy cursor interface by default
-    
-    Upstream https://bugzilla.mozilla.org/show_bug.cgi?id=1876366#c16
-    hints that we could re-test this once we have GTK 3.24.42 (with the
-    now-current gtk3-3.24.41 the original problem is still reproducable,
-    but toggling this flag does fix it for me)

-commit 46a89fb0319d673b3139a068e3d89aed9f44fc16
-Author: Christoph Moench-Tegeder <cmt@burggraben.net>
-
-    use gdk legacy cursor interface by default
-    
-    Upstream https://bugzilla.mozilla.org/show_bug.cgi?id=1876366#c16
-    hints that we could re-test this once we have GTK 3.24.42 (with the
-    now-current gtk3-3.24.41 the original problem is still reproducable,
-    but toggling this flag does fix it for me)
