Pale Moon is the work of a single individual, using contributed Open Source code to create a full-featured, speed optimized version of the popular Firefox browser. Having seen the advantages on other systems (e.g. Linux) with regards to programs being compiled specifically for the capabilities of the machine it is installed on, it became obviously clear that Windows users were at a disadvantage: Mozilla only releases windows executables with maximum compatibility in mind, meaning that Firefox is made to run on as many different systems as possible, sacrificing efficiency and speed in the process to be compatible with, by current standards, absolutely ancient hardware.
Pale Moon is a middle road, cutting away support for ancient systems to achieve a significant speed and efficiency increase, but not trying to squeeze the last few percent more out of it by limiting the range of systems it will run on even more. It aims to not waste computer resources and power on inefficient programs, while at the same time serving a wide range of systems that are currently in use around the world.
Reviewing 27.1.0 (Feb 13, 2017)
Absolutely terrible. Earlier versions of Pale Moon were very, very good. Have switched over to Cyberfox for all my browsing needs.
Reviewing 26.4.0 (Aug 24, 2016)
Really liked the earlier versions. Too many issues with websites with Pale Moon using the Goanna engine. Prefer Cyberfox.
Reviewing 26.4.0 (Aug 24, 2016)
Ever since Pale Moon starting using the Goanna engine, many sites I use on a daily basis don't recognize it. Especially the site I use for my online daily banking. Don't have this issue at all whilst using SeaMonkey, Firefox, Cyberfox, K-Meleon. The earlier versions of Pale Moon were very, very good. And no, I'm not a Pale Moon hater. Not at all. The browser does show promise, IMHO it just needs further work. Will check in on newer versions and check the progress.
Reviewing 26.1.1 (Mar 4, 2016)
Is Pale Moon EVER going to work properly with MOST websites? And will they EVER update their ad blocker extension so that the browser doesn't take forever to load?

still using the Goanna engine
Pale Moon doesn't start (error message when starting)
Make sure your system meets the requirements to run Pale Moon. The most common occurrence of this error is trying to run it on a PC that doesn't meet the system requirements. If you have an Athlon XP or MP machine or a Pentium II or III, this browser will not run. Because Athlon XP is very popular, there is a version of Pale Moon specifically for those PCs [here], but the main version of Pale Moon won't run on it!
Pale Moon for Athlon XP
Note: these builds are a courtesy, and may be updated later than the main browser build.
By popular demand, these browsers were built specifically for the Athlon XP or Athlon MP processors, since Pale Moon does not support these processors by default. These browsers are not as highly optimized as the standard Pale Moon browser, and were about 7-9% slower on the machine they were tested on than the standard Pale Moon in a synthetic test. Compared to Firefox, this is still a huge speed increase.
