New version has been released, with removed dependencies on dxgi in libGLESv2. Simply install VC 2015–2019, or if you don’t want to install it, just copy the relevant files. DWrite is also included.

It looks like we've managed to identify the cause of the virtual memory leak on XP x64. It turns out to be GigaCage, which has been enabled by default since version 92.0.4486.0.

No, he'll just create a new repository where he'll (apparently) upload versions that work starting with Windows XP. He responded to this in the post below.

For now, the version is v91, and they’ll keep updating it until they reach the current version (or run into a problem they can’t solve), while version 91 is just a test version to show that progress is being made and to see how it works in general. Chromium for XP also started out as these kinds of test builds, and once they managed to bring the version up to the current one, the old repository was archived and a new one was created, which already supports XP+.

I guess the way I look at it is:  we had a perfectly good compilation of current Firefox in both release and ESR flavours that already worked on Windows 7 and 8x.  That's all I want.  XP and Vista can now be damned whereas 7 and 8x can be more easily made to work.

I'd be happy if e3k-etc  could just release a more up to date version of v140 ESR.  He already has it working with with v140.0.11, so just recompile the next one.  Sigh!
