I tried with FF48 on Win 7, I can't reproducethe crash. Do you have a crash report in about:crashes or a stacktrace?

Sorry, the user agent is unrelated: I'm actually running Firefox 47 but this has been happening since version 46 or even earlier.
The crash reporter has been disabled in my distro package. I'm rebuilding Firefox now.
I couldn't make it to submit the crash report due to a missing dependency but I uploaded it here: https://gist.github.com/rnhmjoj/fd37e8afbda9ff96ca363f32a566b01f
A regression range would be great.

Firefo47 crashes : bp-ac0287e0-e4ce-4174-ae95-238c92160618
But Beta48b1 did not crash.
So, this seems to be duplication of Bug 1266341.

@reporter, 
Could you test this with [1]Beta48b1?

Yes, that's it. It no longer crashes in 48.0b1.
