$ google-chrome
libva error: /usr/lib64/dri/iHD_drv_video.so init failed
[22345:22345:1110/012603.371456:ERROR:sandbox_linux.cc(374)] InitializeSandbox() called with multiple threads in process gpu-process.

However, it turned out to start chrome as root:

Actions, presumably after which everything broke ...

sudo apt-get update
sudo apt-get install arduino
sudo groupadd uccp
sudo usermod -a -G uccp dvr

At the same time, I tried to create a new user and launch browsers from under it. did not help

Answer 1

Saved by reinstalling the browser

Answer 2

you can try to run firefox under strace and then carefully read the log from the end in search of access errors. Something like that:strace -fvo trace firefox

Answer 3

You can try looking at about:crashes in FireFox and post the report here

Answer 4

Looking at the description, after launching from other users, the rights to browser profiles broke. Try assigning your user as the owner:
sudo chown user:user /home/user -R
