I didn't mean to start flame wars about browsers in this thread. Microsoft gives awesome reading tools in Edge, the reading mode and read aloud, puls now the bing copilot. I use it for reading web content, it's the best browser for that task.
PS. If you believe a user mode process can trash the OS, I wonder what kind of OSes you're using, DOS
Running applications, sharing hardware resources, and protecting the OS and other apps is the primary task of all modern operating systems, whether desktop or embedded. If an app causes system crash it means a serious bug in the system configuration, driver, or hardware itself. Normally misbehaving apps are simply terminated by the OS with no harm to the surrounding.
