In about:config you can change an option named sandbox.readpath.whitelist or similar. Set it to /gnu/store/ (with a trailing / which means recursively) to allow access to the store, where icecat can find its webgl libraries. Then restart the browser. We should add that by default (or something more restrictive) but I don't know how.

I can reproduce the problem; it seems that WebGL is now a required by youtube when using Icecat 68? That's strange because the same video plays fine in an older version of Icecat (but I have to reload the page to get it playing). Anyway, the problem seems to have more to do with Youtube than HTML5 playback in Icecat. A random HTML5 video playback test site [0] may help to convince you of such :-) You could try enabling WebGL in your Icecat (disabled by default) by visiting the "IceCat-specific privacy settings" of the Settings page and checking "Enable WebGL". That didn't work for me, as my driver seems blacklisted by Mozilla. I tried force enabling it with suggestions from this page [1] but your link would still wouldn't be happy with my WebGL support.

Re: Lazy users and updates
It looks like it is not a technical question at all. Organizational may be. You can see which packages are obsolete and to remind users to renew them. пт, 27 дек. 2019 г. в 16:30, Todor Kondić : > Given the user-centric approach of Guix, it feels like it should be up to > individual users of a shared system to deal with installations and the > system updates.

I feel like this is overriding their free will for their own good. Note that the question is ethical, as much as technical :) Ask your users what they prefer. I'd want to handle this myself, but many of my colleagues would prefer an admin to take care of all updating. We are all different :-) Cheers, Konrad.
Lazy users and updates
Given the user-centric approach of Guix, it feels like it should be up to individual users of a shared system to deal with installations and the system updates. But, what to do when they are lazy, or too novice for fiddling with the command line? Do I use the admin's prerogative and set their own crontabs to pull and "package -u" once in a while? I feel like this is overriding their free will for their own good. Note that the question is ethical, as much as technical :)
