Hey reporter, it's not clear to us how you get the problem.
Can you please explain if this happens at the first page or after a long time of browsing?
Also we don't see anything suspicious on the about:memory dump that you shared.

Therefore, could you make sure the following information is on this bug?

If the problem happens only after some time, you can try to get a profile or about:memory dump before firefox hangs completely.

Thank you.
