Let me answer your question although I'm not Tete.
To put things simply, you don't have to switch to SSE build if you're using SSE2 build with no problem. There is not as much difference as you can feel using Firefox.)
(Read below if you want to know more about it.)
SSE2 is one of the instruction set extensions like SSE. If your CPU is capable of SSE2, you can make the program work faster using SSE2.
Some CPUs can get slower using SSE2.
However, I recommend you to continue using SSE2 build unless you are the type of person who can get stressed out over such small things. There is not much difference in performance even if you use SSE2 build with CPU that can get slower.
(Just for your information)
CPUs that work faster with SSE2
・Intel Corei3, i5, i7
・Intel Core2duo, Core2solo, Core2Quad
・Intel Pentium4
・Intel Celeron based on Pentium4, Core2Duo(Solo, Quad)
・AMD Athlon II (X2, X3, X4)
・AMD Phenom or Phenom II (X2, X3, X4)
If your CPU is one of these, you should use the SSE2 build to run Firefox faster.
CPUs that can get slower with SSE2
・Intel Pentium M
・Intel CoreDuo, CoreSolo
・Intel Celeron based on Pentium M and CoreSolo
・AMD Sempron
・AMD Athlon (X2)
・AMD Athlon 64 (X2)
If your CPU is one of these, you should use the SSE build to run Firefox faster.
