librewolf does not have much developer capacity to maintain such heavy patches. you may remember some chromium forks telling they will maintain a patch when google completely removes this API from chromium, but it seems none of them will follow through. I can't really fault them because it is likely a gargantuan task. but I'll fault them for claiming something they (should) have known they can't deliver. but my point is if vivaldi and others can't keep it, how could librewolf?
