The two forks of Pale Moon for Windows XP

This was posted as a reply at Google Product Forums. This concerned video stopping every 25 minutes on YouTube during HTML5 playback.

I got to test a long-form YouTube video with New Moon 27.6.0a1, and the 25-minute video lag still happens.

At that point (when video stops during playback), I pause, or move the video progress indicator back a little to keep the video going.
I treat the breaks every 25 minutes like the breaks during tv ads

I'm most likely stuck with that video lag stoppage, as I've chosen to keep a fork of Pale Moon Moon 27.6.x, because that branch still supports cookie prompting.

There are two forks of Pale Moon for Windows XP:

* New Moon — available at RT's Free Soft blog at Blogspot.
This browser is not my main driver.
* MyPal. Of the two, MyPal 27.6.2 is a somewhat later release than New Moon 27.6.0a1, so I just might consider replacing New Moon with MyPal.

The positive side is, that unlike Firefox, the forks support H.264 video, which should play most videos on YouTube, and clips on twitter.

To switch on support for WebM/VP9 in New Moon 27.6.0a1, one can uncheck "Use MSE asynchronously", and then check "Enable MSE for WebM video" in the Content section of the Options window.

Newer versions of forks most likely have H.264 support as built-in. Older versions of New Moon require extracting the lav extension file(s) from lav.7z into the folder where the browser is installed in Program Files.

It should be noted, that New Moon and MyPal 27.6.x are older versions, but support a few bits more functionality than a comparable version of Firefox (38.8).
