Firefox - "little" problem

After “zypper dup” my Firefox looks like this:

Console:

firefox  
_IceTransSocketUNIXConnect: Cannot connect to non-local host localhost
_IceTransSocketUNIXConnect: Cannot connect to non-local host localhost

How to resolve my problem?

Cleaning ~/.cache/plasmashell/qmlcache may help

It did nothing.

I cleared ~/.mozilla/ and it helped.

I also have this problem. I had to reinstall Tumbleweed recently and Firefox was working OK. Now today I just get this same error message.

Cleared ~/.mozilla, now working.

start firefox with --safe-mode and clean it using its tools could help too i think. But i’m not 100% sure
