Nintendo Switch does not have a normal Internet Browser for user usage. However, there is multiple browser applets. It is the [https://web.archive.org/web/20170304075230/https://gl.access-company.com/news_event/archives/2017/170303/ NetFront NX] browser, which is based on Webkit.

When linking the Nintendo Account with Facebook, the Facebook Auth website will open, offering a search box that can be used to browse the Internet ("LoginApplet"). Alternatively, it can be accessed with ~~[https://gbatemp.net/threads/web-browser-kind-of-on-the-switch.463094/~~ custom DNS settings] which simulate a Wi-Fi login page ("WifiWebAuthApplet" for captive-portal).

When linking the Nintendo Account with Facebook, the Facebook Auth website will open, offering a search box that can be used to browse the Internet ("LoginApplet"). Alternatively, it can be accessed with custom DNS settings which simulate a Wi-Fi login page ([[#WifiWebAuthApplet|WifiWebAuthApplet]] for captive-portal).

At some point WebApplet started sending header "Upgrade-Insecure-Requests: 1" with all plain-HTTP requests (unknown whether other applets affected). This is only for server-use: plain-HTTP content and redirects to plain-HTTP URLs are still allowed (at least on S1).

The full UA for Switch and Switch 2 are similar, on matching system-versions. The NF and NintendoBrowser versions are newer for S2 however.

The conntest URL from [[#WebWifiPageArg]] is used to poll whether the connection is usable, with the SDK [[libcurl]].

In later versions the above domain was replaced with [[Network|ctest.{...}]].

[8.0.0+] <code>malloc</code>/<code>operator new</code> now checks the return-addr (addr located in a relevant NRO), with wkc_malloc_crashonfailure being called for the allocation if the check passes, otherwise a normal allocation is done (the code which runs for this will Abort if allocation fails).

<code>malloc</code> passes the input size directly to the called func. <code>operator new</code> when handling normal non-wkc allocations passes the following to the called func: <code>sxtw x1, {inw0}</code> (for wkc allocations the size is passed directly).

* Looks for AlbumEntry{N} TLVs, when a TLV is not found it is written, then the associated AdditionalMediaData{N} TLV is written the same way as AdditionalMediaData0. If all AlbumEntry{N} TLVs already exist, this returns without writing anything.

TransferMemoryEnabled: sdknso only exposes this for the Web applet. The sdknso func uses <code>nn::os::QueryMemoryInfo</code> at the start of the func, however the output is unused. The applet doesn't seem to parse this TLV.
