Pale Moon 27 was released today: https://forum.palemoon.org/viewtopic.php?f=1&t=13717

Adobe Reader officially dropped support for Windows XP as of 10.1.12 and 11.0.09, so anything beyond that is not guaranteed to work. Adobe states, "You can continue to manually install and update Acrobat and Reader on XP, but future updates will not have been tested on XP and technical support will end for that platform." http://www.adobe.com/devnet-docs/acrobatetk/tools/ReleaseNotes/index.html#x

I think Opera only released 12.18 so they could prove to their new Chinese owners that the Presto rendering engine is still an actively supported product. I still use Opera 12.1x on a daily basis. Some sites no longer work well with it, but otherwise it is still a very lightweight, flexible, and capable web browser.

Since version 25, Pale Moon has become its own independent browser. It mirrors Mozilla's security updates, but is not based on Firefox anymore. Pale Moon continues to provide an XP compatible version, at least for the time being. And then there's also K-Meleon and SeaMonkey, both loosely based on Mozilla, but not really Firefox clones anymore. Maxthon also still supports XP and Vista, at least according to the articles I've found, although they don't state any specific system requirements on their site.

Why would anyone want to use MSE even if it is still supported? It is a total RAM and CPU hog and its protection is mediocre at best. There are free anti-virus programs with better protection and much lower system resource requirements which still fully support Windows XP. I recommend Comodo and Panda.

The Vivaldi browser (based on Chromium, made by the original developers of Opera) has also dropped support for Windows XP and Vista and older versions of Mac OS: https://vivaldi.net/en-US/teamblog/105-snapshot-1-1-453-6-further-tab-closing-options-improved-dark-ui-and-more-import-options "Goodbye to old Operating Systems With Vivaldi version 1.1 we will drop support for Windows XP, Vista and versions of MacOSX below 10.9. Recently, the Chromium project dropped support for these older OSes (Operating Systems), since they are no longer actively maintaned by Microsoft and Apple. As Vivaldi is a small team at present, so we cannot afford to support these OSes seperately. If you are able to, upgrading your OS is the best course of action to ensure secure browsing and access to the latest Vivaldi features and fixes. If not, Vivaldi 1.0 will continue to function, though it will not receive further security updates."
