caused by HWA? Ranking is now down to 70+ - so probably either users left, found a solution or they stopped crashing Note: approx 1/3 of crashes are not startup. Majority of these have different stack starting at frame 1 For example bp-f6f7cd0c-9a02-4e6c-aa37-a34cd2150120 0 dwrite.dll FindElementCommon(ICacheReference*, bool, CacheHeader const&, unsigned int const*, HashElement const*, void const*, IElementKey const&, CachedElementData*) 1 dwrite.dll ClientSideCacheContext::FindInSharedCache(IElementKey const&, CachedElementData*) 2 dwrite.dll ClientSideCacheContext::FindElement(IElementKey const&, CachedElementData*) 3 dwrite.dll ElementTaskList::GetElementData(IBaseCacheContext*, IElementKey const&, CachedElementData*) 4 dwrite.dll IBaseCacheContext::GetElementData(IElementKey const&, CachedElementData*) 5 dwrite.dll FontFaceElement::FontFaceElement(IBaseCacheContext*, FontFaceElementKey const&, DWRITE_FONT_SIMULATIONS) 6 dwrite.dll DWriteFontFace::DWriteFontFace(DWriteFactory*, FontFaceElementKey const&, DWRITE_FONT_SIMULATIONS, IDWriteFontFile*) 7 dwrite.dll DWriteFontFace::Create(DWriteFactory*, FontFaceElementKey const&, DWRITE_FONT_SIMULATIONS, IDWriteFontFile*) 8 dwrite.dll DWriteFont::CreateFontFace(IDWriteFontFace**) 9 xul.dll gfxDWriteFontEntry::CreateFontFace(IDWriteFontFace**, DWRITE_FONT_SIMULATIONS) gfx/thebes/gfxDWriteFontList.cpp 10 xul.dll gfxDWriteFont::gfxDWriteFont(gfxFontEntry*, gfxFontStyle const*, bool, gfxFont::AntialiasOption) gfx/thebes/gfxDWriteFonts.cpp 11 xul.dll gfxDWriteFontEntry::CreateFontInstance(gfxFontStyle const*, bool) gfx/thebes/gfxDWriteFontList.cpp 12 xul.dll gfxFontEntry::FindOrMakeFont(gfxFontStyle const*, bool) gfx/thebes/gfxFont.cpp 13 xul.dll gfxFontGroup::FindPlatformFont(nsAString_internal const&, nsACString_internal const&, bool, void*) gfx/thebes/gfxFont.cpp 14 xul.dll gfxFontGroup::FontResolverProc(nsAString_internal const&, void*) gfx/thebes/gfxFont.cpp 15 xul.dll gfxWindowsPlatform::ResolveFontName(nsAString_internal const&, bool (*)(nsAString_internal const&, void*), void*, bool&) gfx/thebes/gfxWindowsPlatform.cpp The earliest crashes I find are 31.0 beta, build 20140613002318. Most have the stack above, but unlike those of today they were mostly startup crashes. For example bp-3a0932d2-0e5e-4de4-8a68-24c752140707 Some early crashes have d2d1.dll on the stack, like bp-83671b3e-33d8-4ab1-8d9d-def7b2140723. I haven't seen this in current crashes

(In reply to Wayne Mery (:wsmwk) from comment #1) > caused by HWA? Yes, I think so. There are lots of the crashes on firefox too. One example is: https://crash-stats.mozilla.com/report/index/1ca3cd02-c458-490b-a251-119b02150120 And most of the crashes are Chinese locale.
