The goal of Mypal

Mypal strives to provide a current, secure, and reliable browser for Windows XP.
Many computers are still useful despite their age, but would be bogged down by modern operating systems like Windows 10 that are much more resource intensive than Windows XP, or don't support the hardware.

Unfortunately, many developers choose not to support Windows XP due to its age.
In contrast, the Mypal developers offer a fully up-to-date browser, to make that old computer useful again!
