In short, this is a build of Pale Moon designed for computers with 32-bit x86 processors lacking the SSE instruction set. These include the Pentium II and earlier processors from Intel, and the first-model Duron (Morgan core), Athlon, and earlier processors from AMD.
Unless your CPU is 15 years or older, this variant of Pale Moon should not interest you.
Following up from a series of posts in the Pale Moon SSE thread, the thread you're reading now is the official location for any questions, reports, and comments about Pale Moon for IA-32.
Please be aware that, unlike the Pale Moon SSE builds, builds for IA-32 may be late or sporadic. They may be discontinued at any time without warning.
