Pale Moon Has Jumped the Gun

No XP for you! It was already known that the forthcoming milestone release (as of version 27.0) was not going to accommodate XP users. But now we find out that v26.5 is also dropping XP support. So it's earlier than expected.

this is version 26.5, not sure if there will be any more versions.
and it is only for 32 bit.

Actrually the Atom version has been the only game in town for awhile on XP (as far as Pale Moon is concerned). So my understanding is that is you are running the Atom version, do not upgrade to v26.5.

 

Hmmm, my version installed is 26.5 and everything works so far. I use palemoon as my secondary browser especially for anything dealing with youtube. My primary browser is firefox, the latest version is 50.

above from here

so still okay for awhile, but will probably have to go to a sandbox after 2016 ends,
