TB - Last version to work on non-SSE2 Machines

[L.A.R. Grizzly]

What was the last version of TB that will work on a non-EES2 machine? I currently have TB 45.8.0 installed. Thanx.

Firefox 48.0 was the last Release to still run on Windows that was using a CPU that did not support SSE2 so Gecko 49.0 and later.

Since Thunderbird follows ESR sort of Releases the 45.8.0 is the last (for Windows).

However on Linux Thunderbird 52.x can still work on old CPU's that does not support SSE2 unless otherwise.

Ended Firefox Linux support for processors older than Pentium 4 and AMD Opteron

Thanks for the heads-up! I guess I have the latest for my older machine. She's old, but still works great.
