ASAN Nightly of 2018-07-19 about:support has the first large box with general config filled, but every other detail is completely empty. Copy pasting the raw output gives a ton of data, of which this looks like it might be relevant: "crashes": "Troubleshoot data provider failed: crashes\n[Exception... \"File error: Not found\" nsresult: \"0x80520012 (NS_ERROR_FILE_NOT_FOUND)\" location: \"JS frame :: resource://gre/modules/Troubleshoot.jsm :: crashes :: line 646\" data: no]", "sandbox": "Troubleshoot data provider failed: sandbox\nTypeError: Cc['@mozilla.org/sandbox/syscall-reporter;1'] is undefined",

This does not happen in an empty profile.

about:crashes gives Hmm. That address doesn’t look right. Please check that the URL is correct and try again.

The first error looks like this line: https://dxr.mozilla.org/mozilla-central/rev/085cdfb90903d4985f0de1dc7786522d9fb45596/toolkit/modules/Troubleshoot.jsm#646 which is let CrashReports = ChromeUtils.import("resource://gre/modules/CrashReports.jsm").CrashReports; but it's correctly inside an AppConstants.MOZ_CRASHREPORTER check... > "sandbox": "Troubleshoot data provider failed: sandbox\nTypeError: > Cc['@mozilla.org/sandbox/syscall-reporter;1'] is undefined", This seems to be because the sandbox syscall reporter is missing. I don't know why that'd be but you've reviewed some of that code so you probably have a better idea than me... I'm a bit surprised generally because I think we tried to make about:support not be so brittle even if one of the data reporters failed, and the errors bear that out but you're saying the entire thing is still empty? Nothing shows up at all?

(In reply to Gian-Carlo Pascutto [:gcp] from comment #2) > TypeError: $(...) is null[Learn More] aboutSupport.js:133:7 This is probably why the page is empty... this is well weird, because it's looking for #crashes-title, which is here: https://searchfox.org/mozilla-central/source/toolkit/content/aboutSupport.xhtml#292 which is also behind a MOZ_CRASHREPORTER check. Presumably I'm missing something, because at a glance this looks like some kind of frankenbuild where some parts think the crashreporter exists and other parts don't.

(the access for that being here: https://searchfox.org/mozilla-central/source/toolkit/content/aboutSupport.js#127-134 , also behind a MOZ_CRASHREPORTER check) If you put `AppConstants.MOZ_CRASHREPORTER` in the browser console, what comes out?

AppConstants.MOZ_CRASHREPORTER true

I unpacked this over the regular Nightly install. I don't know if that is an issue or not, because an empty profile works. about:buildconfig Built from https://hg.mozilla.org/mozilla-central/rev/690cb3015db6645b335ac4835a50073cb6a3e23c /builds/worker/workspace/build/src/clang/bin/clang -fgnu89-inline -B /builds/worker/workspace/build/src/gcc/bin -std=gnu99 6.0.0 -Qunused-arguments -Wall -Wempty-body -Wignored-qualifiers -Wpointer-arith -Wsign-compare -Wtype-limits -Wunreachable-code -Wunreachable-code-return -Wclass-varargs -Wloop-analysis -Werror=non-literal-null-conversion -Wstring-conversion -Wno-error=deprecated-declarations -Wno-error=array-bounds -Wformat -Wformat-security -Wno-gnu-zero-variadic-macro-arguments -fsanitize=address -U_FORTIFY_SOURCE -fno-common -fno-strict-aliasing -ffunction-sections -fdata-sections -fno-math-errno -pthread -pipe /builds/worker/workspace/build/src/clang/bin/clang++ -B /builds/worker/workspace/build/src/gcc/bin MOZ_AUTOMATION=1 --enable-update-channel=nightly MOZILLA_OFFICIAL=1 '--enable-optimize=-O2 -gline-tables-only' 'CC=/builds/worker/workspace/build/src/clang/bin/clang -fgnu89-inline -B /builds/worker/workspace/build/src/gcc/bin' 'CXX=/builds/worker/workspace/build/src/clang/bin/clang++ -B /builds/worker/workspace/build/src/gcc/bin' --enable-address-sanitizer MOZ_STDCXX_COMPAT=1 --enable-valgrind --enable-js-shell --disable-profiling RUSTC=/builds/worker/workspace/build/src/rustc/bin/rustc CARGO=/builds/worker/workspace/build/src/rustc/bin/cargo RUSTDOC=/builds/worker/workspace/build/src/rustc/bin/rustdoc RUSTFMT=/builds/worker/workspace/build/src/rustc/bin/rustfmt LLVM_CONFIG=/builds/worker/workspace/build/src/clang/bin/llvm-config --enable-rust-simd --enable-address-sanitizer-reporter --disable-elf-hack MAKE=/usr/bin/make --disable-crashreporter --disable-install-strip Downloaded from: https://archive.mozilla.org/pub/firefox/nightly/latest-mozilla-central/firefox-63.0a1.en-US.linux-x86_64-asan-reporter.tar.bz2

This is fixed in the current build.
