I didn’t have the problem with ddg. I did have a problem with startpage though, and for some reason, the clearnet address is used in the default search engines list. (I also find it really strange that it has google because that can apparently fingerprint you? but maybe it prevents this somehow)
I don’t really agree with the point about “ changing the default setting really should reset those preferences”. It’s really nice that you can choose different security levels for different websites, and you can check which sites have custom security levels in the settings. It doesn’t make sense that changing your default would delete all your exceptions.
I’m kind of still wondering about how private is Onion browser though. Does it offer any real advanced fingerprinting resistance? The way that Tor describes it (“ Apple requires browsers on iOS to use something called Webkit, which prevents Onion Browser from having the same privacy protections as Tor Browser.”) is a bit unclear, but I thought that it still protects against most tracking. “If… you’re not concerned with being tracked down, this is a perfectly reasonable choice on iOS.” makes it sound really bad.
With Orbot it should have good IP leak protection, but it is not really going to have any advanced fingerprinting resistance, no.
In that case, shouldn’t its description get changed?
“Onion Browser is an open-source browser that lets you browse the web anonymously over the Tor network on iOS devices and is endorsed by the Tor Project.”
