Thanks for taking the time to answer! I did read the Flexlauncher docs which also recommend the Chromium command, I was hoping there’d be something like that for Firefox because it’s just a matter of time before ad blockers become handicapped in Chromium. But guess that’s the only solution then.
Doesn’t appear to.
But looks like even GNOME Web supports extensions now. So no reason that something like uBlock origin couldn’t be implemented right?
