In-app browsers are like standalone web browsers without the interface – they rely on the native app for the interface. They can be embedded in native platform apps to load and render web content within the app, instead of outside the app in the designated default browser.
in-app browsers, without notice or consent, “ignore your choice of default browser and instead automatically and silently replace your default browser with their own in-app browser.”
In August 2022, developer Felix Krause published a blog post titled “Instagram and Facebook can track anything you do on any website in their in-app browser.” A week later, he expanded his analysis of in-app browsers to note how TikTok’s iOS app injects JavaScript to subscribe to “every keystroke (text inputs) happening on third party websites rendered inside the TikTok app” but, according to the company, never uses that keylogging code.
“If someone is interested in some content an app has linked to and displays in an embedded browser, I’d recommend copying the link and pasting it into a dedicated browser, which has more granular privacy settings that can be toggled.”
Switch to a secure browser. The process varies by app, but if you find yourself on a website while using an app, try to find three dots or a Settings button. Tap that button to open a Settings menu. One of the options may be “Open in Browser.” If you don’t see any Settings menu options, simply copy and paste the URL from the browser’s address bar into your chosen browser.
Use the web version of a service. You can also stop using the app altogether, which may be a good idea if you want to reduce the amount of personal information you share on social media.
Yeah, I’m not actually too concerned about the Mlem built-in on iOS. I do try to avoid the one in Facebook/Instagram and move anything I actually want to do to my real browser. I just mainly thought it was funny in the moment.
