 recompiling an ESR52-based Tor Browser with the mingw-w64 toolchain we use
 for ESR60, no? If so, let's do that.

 firefox compile step. I started with the tbb-8.0a8-build1 tag and applied
 the patch from #25554 (4c1f78c312aa10ff54e5b07de4ef3278ab2ed01e). Here is
 a portion of the log; has anyone seen this kind of error before? Maybe I
 need other changes from the ESR60 era?

 but I am out of time for now to try to decipher the conversation in the
 bug.

 You need to compile with `--disable-accessibility` as there is a bug in
 newer mingw-w64 versions that is not figured out yet if accessibility is
 enabled.
