 > I talked to a Windows user today on #tor who uses a screen reader and
 was reporting that Tor Browser 8 doesn't work for them. They reported that
 the Firefox ESR does work for them.

 build with mingw, for reproducible build purposes?

 Yes and no. The reason for the bug is that mingw-w64 does not support the
 new accessibility related code in Firefox (widl is the problem here, to be
 more exact) *regardless* if you are using clang with it (which we will be
 doing soonish) or GCC (which we are doing now) as the compiler. mingw-w64
 "just" provides the Windows headers etc.
