Implementation notes:

The global user-agent override was moved to the networking component where it is actually implemented. The new preference name is network.http.useragent.global_override. Please note that using a blanket override is normally (very) counterproductive and does not, in fact, help much with privacy. It would also override the compatibility modes (Native/Gecko/Firefox) in Pale Moon. As such, the browser will now warn you if the user-agent is globally overridden (in preferences) and allow you to easily reset that override and re-enable the various compatibility modes.
Module scripting caused some persistent and very hard to track browser crashes that we've narrowed down to a specific optimization in the JavaScript JIT (Just-In-Time) compiler (IonMonkey). This optimization is now disabled by default but if you need that little extra performance (usually only noticed in very optimized code or some benchmarks) then you can re-enable it, trading in stability, by setting the new preference javascript.options.ion.inlining to true.
Prohibited ports: Pale Moon maintains a blacklist of ports the browser may normally not connect to on servers, to mitigate abusive web scripting employing your browser as an attack bot on servers (e.g. by connecting to mail servers or what not), NAT slipstreaming, and similar security issues. To more thoroughly prevent known abusable ports on servers, this list was extended with a number of additional default ports for various non-http protocols.
Downloaded files without a file extension: When a file without an extension is downloaded, we will now open the download folder where you may choose to take any specific action manually, instead of trying to execute it as a program or through an associated program.
