I have ancient PC, only SSE1 support in AMD Sempron. My mainline Firefox supported ended in 2016 at 48.0.2

I was never migrated to the ESR line ( ver 45 on I believe).

What is the best ESR release to go for now, (that has better stability than that of mainline 48.0.2 I currently use)?

Did SSE1 support end at ESR 45.2.0? (which I think I have found off Sourceforge)

Any ideas? Thnx

OK, found the Firefox ftp site. Deduced that ESR 45 continued releasing for ~9mnths to 45.9.0 on 17 Apr 2017. So going with that installed into a separate directory and all seems well.....

Firefox 49.0 and later on Windows has required CPU's that support SSE2 and has actually been a recommendation in system requirements since Firefox 4.0

Firefox on Linux has required CPU's that supported SSE2 since Firefox 53.0 and later. So if you were using Linux then you have the Fireox 52 ESR option. Though Fx 52.9.0esr out on June 26 will be the last major update for 52 ESR.
