Safety Checklist:

Before proceeding, a short legal note. You must own a legitimate copy of Minecraft Java Edition to play version 1.5.2 legally.

Crucially, 1.5.2 existed during the era when Minecraft could still be played in a web browser via the minecraft.jar applet. Although Mojang eventually moved to the standalone launcher (and later discontinued browser support entirely), the .jar files for versions like 1.5.2 were widely distributed. This open distribution is the foundation of their modern availability on proxy sites.
