I know this is a Windows release but I guess for my limited use 2 cents with DuckDuckGo (DDG) browser for macOS:

• It is enjoyable and quick to use.
• No extensions but with its protections feature, there are no ads?
  • However, compared to Firefox with my extensions setup, vanilla YouTube on DDG is way more crowded and distracting.
• Duck Player plays YouTube videos without trackers and ads.
  • But it does take you to another page. No biggie for me though.
• Haven't used its fire proofing feature yet (a white list for saved accounts/passwords to prevent being cleared after using the Fire button feature)

Now, I wouldn't use it as my main daily driver. That's still Firefox, most probably because of my custom firefox css, bookmarks, and extensions setup (especially containers).

But I do use DDG browser once in a while, I guess to just have that fresh feeling of trying the new shiny thing (or just something out different from the regular daily routine). I use it almost like a tor browser-lite, after every session I'm done with using DDG, I click the Fire button/"Clear browsing history".

Might try it for an extended trial for some tasks but I'm using it to exclusively browse the federated communities and as an article reader for focus to mentally separate from the multi-tasking, less than 50 total tabs, hell that is Firefox at the moment.
