In Firefox Safe mode these changes are effective:

• all extensions are disabled
• default theme is used (no persona)
• userChrome.css and userContent.css are ignored
• default toolbar layout is used (localstore-safe.rdf)
• Javascript JIT compilers are disabled (javascript.options.*jit)
• hardware acceleration is disabled

• plugins are not affected
• preferences are not affected

You can try to disable the JavaScript JIT compiler and set javascript.options.*jit to false on the about:config page.
