Pale Moon (64-bit)

What's new in this version:

Fixes/changes:
- Code cleanup: Removed the (otherwise unused) visual event tracer code
- Code cleanup: Removed reflow performance tracing code (telemetry)
- Fixed a key JavaScript bug where defining properties on an object would wipe the object
- This seems to be a common issue with "modern" libraries that use "define" instead of "change" and expecting the other properties on the object to be retained, resulting in "x is undefined" errors all over the place if the object is wiped
- This aligns the behavior with ES6's "Validate and apply property descriptor" pseudo-function
- Updated the SQLite library to 3.8.11.1
- Added support for the element.matches() Web API function
- Added support for BASE tag parsing in source view. Previously, when viewing the source of a document, clickable links would be incorrect if a base path was specified in the document with this tag
- Fixed an issue with running timers after the computer would have been put to sleep with the browser opened
