I updated my FF yesterday and at this point I make sure to check the settings for suddenly "opted-in" "features" I am not aware of. This one also was a big surprise.
If I want to get screwed and sold to the advertisement industry by my browser vendor, I'd simply use Chrome. So please stop it, Firefox.
with this acquisition https://blog.mozilla.org/en/mozilla/mozilla-anonym-raising-t... Mozilla is now an ads company
it's downhill only from here folks
but - as with any software updates, us users always suffer in having to re-check over all options to see what things changed on us (if we're lucky and get an option)
Also, to which tweaks were you referring?
edit: oops, there *is* a LibreWolf Mac port now
Other than that, I dont remember any real differences. Waterfox has been fine for me because of the sync, but if you don't need account syncing, LW is fine.
Even with this, it's still better than chrome.
