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).

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.

[12.1.0+] The size is now passed directly (64bit) without using sxtw.
 
[11.0.0+] There's now optional code for using [[SVC|svcMapPhysicalMemoryUnsafe]] etc, however it's unknown what sets the flag for this. An Abort string used this is: "{path}/TransferredMemoryManager.cpp"

When sending messages, there has to be an available message slot available (<code>max_messages!=message_count</code>), and there has to be enough space available (<code>msghdr_contentsize+0x10 + cur_size <= max_size</code>). After pushing the storage, message_count is incremented and cur_size is increased by <code>msghdr_contentsize+0x10</code>.

When receiving messages, it will repeatedly pop Interactive output storage until no more are available. If the ID is not 0x1000/0x0, the message is ignored. Otherwise:
When receiving messages, it will repeatedly pop Interactive output storage until no more are available. Non-Ack messages are Acked.
* Ack: Verifies that message_count is not already 0, then decrements it. Then cur_size is decreased by the u32 loaded from msgcontent+0.
* Ack: Verifies that message_count is not already 0, then decrements it. Then cur_size is decreased by the u32 loaded from msgcontent+0.
* 0x0: Does some validation. Copies the first 8-bytes from the header to the user [[#SessionMessage]]. Reads the message content into the user [[#SessionMessage]], when contentsize is non-zero. Then sends an Ack with the storage size.
* 0x0: Does some validation. Reads the message content into the user buffer, when contentsize is non-zero. The original contentsize is written to an user output param. The last byte in the user buffer (contentsize clamped to the user max-buf-size, -1) is set to 0 for NUL-termination.

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.
