Well...I prefer privacy, but for now I like and use Opera-it's bookmarks are beautifull, but it's so stupid browser that can't be made to not remember history or delete it...it lacks control-as every other blink browser.
Firefox on the other hand seems to have discarted their philosophy for freedom and now partner with monsters like Soros to ,,fight fake news''. It was Firefox quantum which changed many of the default settings to be anti-private and free. Still it's far better than other browsers and you shouldn't be discouraged to use it. It's the best we have...and when hardened it's great Actually Tor is on the base of FF. You can check how to make it better here https://www.privacytools.io/#browser and here https://www.youtube.com/watch?v=tQhWdsFMc24.
For watching youtube/facebook and most of the account it's better to use Brave.
