I'm seeing same issue "gah! this tab has crashed!" from firefox downloaded from package cluster
yesterday (so: using "latest" in pkg.conf). It usually happens when a site is first loaded. Then reload and it loads the site, and might crash shortly after. Is it a firefox issue?

$ lldb --core firefox.core --file /usr/local/bin/firefox
(lldb) target create "/usr/local/bin/firefox" --core "firefox.core"
Core file '/home/john/firefox.core' (aarch64) was loaded.
