Crash at NSS_NoDB_Init()/EnsureNSSInitializedChromeOrContent() looks like a NSS issue, Daiki can you look at it please?
Thanks.
Comment 4 Vít Ondruch 2019-12-02 09:39:05 UTC 
Just FTR, NSS is one of the packages I have tried to downgrade without luck. This is my current version of NSS:

~~~
$ rpm -q nss
nss-3.47.0-3.fc32.x86_64
~~~
Comment 5 Vít Ondruch 2019-12-03 12:38:27 UTC 
This seems to be related to bug 1778344. I have downgraded to glibc-2.30.9000-19.fc32.x86_64 and FF works it seems.
Comment 6 Florian Weimer 2019-12-03 12:44:34 UTC 
This is already tracked as bug 1778366. I'm waiting for input from the Mozilla developers, sorry.
