Pale Moon has been updated to version 28.14.0. The update is a development and security update. Linux versions will follow shortly.
Note: Included in the updates are DiD* patches.
*DiD stands for "Defense-in-Depth" and is a fix that does not apply to an actively exploitable vulnerability in Pale Moon but prevents future vulnerabilities caused by the same code when surrounding code changes, exposing the problem.
From the Release Notes: This update addresses an intermittent crash in the newly-implemented ResizeObserver API (introduced in 28.14.0) occurring on a number of high-profile and often-used websites.
