New and changed in this version:

Pale Moon 15.3 is an important update that sees a number of under-the-hood changes. The are no functional changes in this update.

Changes:

  • The compiler has been changed to a newer version (Visual Studio 2012). This has a few consequences:

  • Automatic vectorization: If your hardware supports it, more advanced processor instructions are used.
  • Support for multiple cores.
  • The 64-bit version of Pale Moon will no longer support Windows XP.
  • Incremental garbage collection for Javascript.

Bugfixes:

  • Minimize intermediate surface size in Azure to mitigate performance regression.

The author has a vision and sticks to it pretty well, but whether or not his desires align with yours is up to you. Palemoon tends to be conservative with UI changes. Given that the firefox team seems a little unfocused there IMO, this is not a bad thing.
So, more stable front-facing UI and better compiler optimizations for newer CPUs. If you care about that, it's a good choice. If you don't, stick with Firefox.

A bit slow aren't they? Firefox 16 has been out forever.

It doesn't matter. Palemoon 15.3 already comes with many Firefox 16 features, and that's why they deem the version upgrade unneeded.
