+    `https://0.0.0.1` sometimes appearing when attempting to
+    launch Firefox when it is already running (bmo#1892612).

+    selection in some situations for users with the Japanese
+    locale set (bmo#1892363).
+  * Fixed: Fixed text corruption when dragging text containing
+    unicode characters on Linux systems (bmo#1888202).

+    `arguments.length` (and not using arguments otherwise) inside
+    of a generator or async function (bmo#1892699).
+  * Fixed: Fixed an issue that could lead to inconsistent focus
+    handling of `<select>` elements when opened (bmo#1893177).
