I asked jmaher what percentage of our Linux users this is. It's 21%. This doesn't seem small. On top of that, we know that not all distros have telemetry enabled and so we won't be counting those either (Debian is the largest). I don't know how many users we need to keep supporting a platform, but this seems like quite a few people to throw under the bus. > There is not a lot of support in the industry for 32 bit linux, all > the major vendors are only distributing 64 bit versions now and other > browser vendors only distribute 64 bit versions officially.

At least going forward I don't think it's something we want to keep supporting or really worry about right now. So on the Linux side just disabling those tests should be acceptable. The problem seems to be that linux32 and in particular non-e10s is used as a proxy to test other platforms. Fennec was mentioned (and might be fixable), but are there some other non-e10s use cases like Windows with accessibility? Or is that no longer an issue? So indeed then you'd have to move those tests first. -- GCP _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
