i can't load certain sites on firefox, it just gives me a blank white screen. there's no error displayed or anything. some sites load fine (gmail, social media, youtube, etc work normal), but some sites i visit give me a blank screen. they load fine in other browsers and even on firefox mobile, just not on firefox desktop. i've tried deleting the cache for firefox too, but that didn't fix it either. anyone knows what the problem might be? thanks!
