Thanks.
Thanks for making it clear, and sorry for misreading the email. So Milan, did you mean there are over half of people using 32bit Windows not just 32bit Firefox? Is there any data we can see for this? Looked at Telemetry, and found an item called DEVTOOLS_OS_IS_64_BITS_PER_USER, which according to the code, actually checks whether the build is 64bit, not the system. (That checks eventually goes to nsXULAppInfo::GetIs64Bit(), which returns value depends on a compile time macro.) - Xidorn _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
