Comment OpenBSD Chromium (Score 1) 97
There is actually a Chromium package in OpenBSD that uses pledge() and unveil(), and it's interesting. The browser is only able to see your ~/Downloads directory; the kernel will either block or kill it for trying to open anything else.
If Microsoft is serious about Edge, then I would like to see a relevant OpenBSD package. I would also like to see an F-Droid listing.
Barring these, Edge is a Windows-only browser.
