totally-not-spyware VS epiphany

iOS as well - JailbreakMe[0] and TotallyNotSpyware[1] use a WebKit exploit to get out of the sandbox to then trigger other exploits that allow full system compromise/control.

It's probably gonna be gibberish to you but if you want to know how it worked https://github.com/JakeBlair420/totally-not-spyware

Mozilla is just using Firefox's old reputation to market itself as an organisation for Internet freedom, while receiving donations from search engines. People see more advertisements in Firefox than in Chrome and still support Firefox. They forget there is Epiphany.

You can follow its development by yourself here. If you add Planet GNOME to your feed reader you're also extra likely to see such announcements.

Use Epiphany. It uses webkit and thus behaves pretty much the same as Safari for most browser specific bugs.

As far as I can tell, there is no free and easy way to do this unless you own an Apple device. Recently it came to my attention that tools such as Epiphany (Linux) and Playwright (Windows) exist, but even then it's just the rendering engine you're testing, and who knows what weird bugs you might run into.

You might want to take a look at Epiphany[1]. It's just Safari (Webkit, actually), but without the need for Apple devices.

They used to have a port of Safari for Windows. It was as popular as you'd expect. Having said that, WebKit - the engine underpinning Safari - is open source with BSD and LGPL 2.1 compatible licensing (https://webkit.org/project/). In addition, they make the engine available for use on Linux (https://webkit.org/downloads/). Gnome Epiphany is a browser based on WebKit (https://github.com/GNOME/epiphany). According to their manifesto, they support Simplicity, Standards Compliance and Software Freedom. Specifically, "Epiphany opposes the dominance of the web by proprietary software web browsers. Today's chief offender is Google Chrome, a browser that purports to be open source, yet actually includes several proprietary components."

Epiphany development relies heavily on WebKitGTK, some things are out of reach for developers who do a great job. One such problem is the scroll speed. This extension is a workaround for that, please if you can contribute, contribute upstream.
