Hello! I've updated my system having now working Xfce4, this bug was fixed: https://issues.guix.gnu.org/issue/37342
But now I cannot watch HTML5 videos in IceCat 68.3.0esr (64-bit), cause it does not support one of formats video hosting is using. It says: "In current time your browser does not support any of available video formats." All those extensions in Icecat are disabled, so LibreJS, LibrifyJS, Searxes blocker - are disabled. I have a question of how to use this part of the internet and work on GNU Guix simultaneously.
