I’ve installed Firefox Nightly onto my fresh Fedora 33 install and am having a video playback issue, but since the issue doesn’t show up in the standard Firefox installed by Fedora nor the Brave Nightly I’ve installed via dnf & their repo, I’m wondering if it’s a sandboxing issue; that is, I’ve placed my Nightly install in /opt, chmod-ed, and chown-ed it appropriately, but I think I might be missing something.
Any suggestions on where to start would be greatly appreciated and thanks, in advance…
