We need to setup SSE desupport rules on the release channel before we ship 53.0 RC1, see bug 1308167.

Marking this a release blocker now that we're in beta - just so we remember to do it before RC.

We don't have a sumo page to point to the desupport notice to. I wonder if https://support.mozilla.org/kb/your-hardware-no-longer-supported can be fixed so show content for Windows deprecating SSE in 49 and Linux 32 in 53.

Actually, that's incorrect. That url turns into https://support.mozilla.org/t5/Install-and-Update/Your-hardware-is-no-longer-supported/ta-p/39389 in the new sumo, which has correct info for Windows and Linux. #build says we only support Macs with SSE2-capable CPUs via our 10.9 requirement, so the 49.0 text on sumo matches that too.

Rail, is there anything left to do here?

I think we are handling this issue this week.

This should be done now. like beta[1], linux 32-bit users with SSE should receive most recent release version prior to 53.0.

first Firefox-52.0.2-build1: https://aus4-admin.mozilla.org/rules/573
then SSE-desupport page: https://aus4-admin.mozilla.org/rules/574

It looks like this was not set-up correctly. The first rule should've been a watershed - because <52.0 don't send instructionSet at all. It also looks like the blob that the desupport rule points at (SSE-Desupport) has the wrong version set (48.0) - so it never returns the desupport notice. This is probably because that blob was previously used as the desupport blob for Windows, where we desupported SSE earlier. We should've used a new blob with a different version set for Linux.
