I can't say about the rest (the search seems to work well, sometimes it searches better than Google, in rare cases it can be worse), but the email protection option is implemented extremely poorly. I can create an address @duck.com, but if I try to log into it, after logging out or if Firefox decides to logout, most often, either nothing happens after I click “Sign in”, or when I enter a set of words from the letter, an anti-bot check appears, occasionally an error something like “these words are not suitable”. This is incredibly annoying, to say that it is angry is to say nothing. This problem has not been resolved for a year, but previously everything worked. It's a shame that companies that are against GAFAM have to stay ahead of them instead of copying their worst stuff.

I always install Firefox and Duck (including Ducks Browser For more restrictive browsing, needs) as straight up first install on all devices. Unquestionably the best protection from being farmed on the internet.

Samsung farms you, Microsoft farms you, Google has your DNA, Facebook OWNs and SHAPEs your thoughts and hate. This stops all of that. So if it breaks parts of the internet, thats ok too, its called protection.

One of my friends put my email into a shopping website to get some (so called TEMU special deal). Im no longer friends with them. I have throw away shopping emails and he blew a 20year private email I use for formal emails. Thats how hard you need this....

Privacy red flag! Asks for so many permissions not needed for email forwarding

Comoda e veloce soprattutto per Linux in cui non é disponibile DuckDuckGo.

Con l'estensione attiva non mi fa superare la verica captcha di Facebook,
in pratica mi da la verifica captcha positiva ma mi rimanda al login e questo
si ripete molte volte senza consentirmi l'accesso a Facebook.
Il problema si è presentato da 2 massimo 3 settimane, prima non avevo
nessun problema ad accedere.
Disattivando l'estensione supero positivamente la verifica captcha e posso
accedere a Facebook.
Ho aperto anche un Topic nel Forum Mozilla Italia dal titolo:
" Malfunzionamento di Firefox all'accesso in Facebook con il captcha?"
I miei dati attuali: Win 10, Firefox 152.0.1 e DuckDuckGo Search & Tracker Protection
v. 2026.5.22.

Very nice job, great to prevent Google, Meta, Google, Microsoft, Google, and Google from tracking. (Makes a great pair with Ghostery.)

I see no point to this since we have uBlock that's not restricted like on Chrome browsers. Adding AI only makes this worse.

Overall, I'm not happy with FF in 2026 and I understand Mozilla is going to redesign/refresh FF to (try) to win users back. It sits at the bottom of browsers for desktops — then again, desktop browser use is on a major decline anyways.

"Optional" AI summary is on by default. They think changing your search to a "noai" domain is a suitable work around. No it's not, we should not have disinfo brainrot on by default.
