On last commit from nonguix, firefox crashes on opening wasm debugging tab. Is this expectable result, or not?
I can’t speak to the crash, but Firefox’s wasm debugging tools are not as good as Chrome’s, unfortunately.
If Firefox is crashing, then it sounds like a Firefox bug to report so it can be fixed. In my experience, Mozilla developers probably don’t know there anything wrong until the bug is reported, so it’s much more likely to be fixed if you report it.
