This bug is for crash report bp-7ade8c73-37ae-453c-b0f0-3574c0191223.

I have manually switched http/3 on in the config. Visited blog.cloudflare.com I think when it crashed, not sure tho.

Running Fx 72.0b10

Still crashes on Fx72.0b11.

Can pretty reliably crash it by going to https://blog.cloudflare.com

Will this be fixed in 73 or do we have to wait for 74?

Just crashed on 73.0b4 btw.

Please try Nightly.

Doesn't seem to be crashing on Nightly 74.0a1 (2020-02-01).

Using a completely different profile without any extensions tho, will try again with my default profile when Beta updates to 74.

Have to add tho, it doesn't seem like nightly likes using HTTP/3 that much. Most times it just uses HTTP/2. (using it on sites I know support HTTP/3 hosted by cloudflare)

Haven't seen any crashes since updating to Fx74 in the aurora channel. Seems to be fixed!
