Firefox not working anymore

[Phil57]

Hello, I not able to use Firefox with any Webtop image (clean installs), it's not opening, no error, no log that I can see.
Other proot apps that I use are fine.

I cannot replicate please try from a clean file context, you might just have bad files in your mozilla profile for all we know.

Also you can just run firefox-pa from the command line and witness the output, if it shows a pid number or firefox allready running you know you have a corrupted profile state, maybe a stale lockfile somewhere.

I have tested from multiple clean Webtop with 0 data, so no profile already created.

Running from command line does give any output at first start. A second start shows a pid, so it started. It shows also as running on the host in the docker processes.

I'll check if I can find any logs in the Mozilla folder.

Try seccomp unconfined, again I cannot replicate this:

Your kernel/docker setup may be too old for head firefox.

Well in fact it's the opposite of that, I was running seccomp unconfined and removing it make things work. (I don't know why I had it)

Docker and kernel versions are recent.
