End-of-Life announcement for Pale Moon "Legacy" (3.6.x)

1. Functionality: More and more web sites are adopting techniques and code that no longer works in gecko 1.9.2, or cause severe performance issues. This includes large and popular social media sites, blog sites, art sites and most other actively developed web sites on the Internet. As such, the legacy browser is quickly losing ground in terms of being useful for its intended purpose.
   
2. Maturation of the Next Generation code: The Firefox code base has improved significantly in the last few versions and the initial memory problems are all but mitigated. This means that there are ever fewer reasons to keep running 3.6.x, even on lower-end systems. The Next Generation version of Pale Moon performs well in virtual machines, for example (this has been extensively tested).
3. Security: New security patches for problems that also affect gecko 1.9.2 are becoming increasingly difficult to back-port, especially issues related to javascript. There are currently no critical vulnerabilities in Pale Moon 3.6.x, though, so this is a little less of a concern (although this may change at any time). What is more important, however, are add-ons and toolbars that will no longer be updated and have not been updated for a while already. Each unmaintained add-on or toolbar poses a potential risk. Running 3.6.x prevents you from using updated extensions as they are no longer maintained or developed for that version of the browser.
