How do you rate the DuckDuckGo browser on Android?

It's fine. Websites break on it less often than I would have expected and the “nuke your cookies and history" button is a fun feature. I've mostly moved to Firefox, though, just to get away from Chromium (although I realize the irony in that; my fingerprint is almost assuredly far more unique than if I stuck to Chromium).

Never heard of it, what is it based on?

I like the browser. It never seems to break anything. My father uses it also. However, I must use Firefox with its built in Enhanced Tracking Protection in strict mode specifically to prevent Chrome domination.

it's not bad but firefox focus is better imo

The only way I've used duckduckgo browser is for tracking protection feature and to get anti tracking email address. For internet browsing I prefer Mull

It is a good browser, but wouldnt get my location on degoogled lineage so i went to fennec. I submitted an issue to the ddg github about it and the response (after 3 months) was to brush me off because it worked fine with play services. Not encouraging for sure.

It's the only browser I use. I like it because the only links I open are if I click a news article or something on social, and it auto-nukes history and cookies.

it's pretty good! I wish it had support for PWAs though

I like it. I tend to use it more than Firefox recently. It seems to load most sites faster.
Not having a bunch of tabs remain open all the time is great. FF refuses to close them no matter what setting I use, and I always forget about them so it'll have like ten tabs in the background for no reason.
I also dgaf about what I searched for or where I went previously, so not having a history is great.

FF is mainly my YouTube app.
