Forum Discussion
There should be a separate category Linux here
The matter is what is good for Windows OS platform is not always or at all good for Mac OS or Linux. What might be a solution for the Mac OS might be good for Linux and vice versa, for they are Unix based.
The other matter is this an Insider discussion, so there would be very few, if at all Windows Insiders in the Linux world.
Also, MS still can't get out a stable release of Edge for Linux, which is why this forum/discussion should specially invite them to test the browser. All other browsers based on Chromium have stable releases for Linux, and they did that immediately.
Just got a email from Vivaldi, (image below), already on every platform.
By the way, Edge web capture saves files in .jpeg, but they cannot be uploaded to this place.
Vivaldi have the most buggy stable version i ever seen, microsoft will not out a unstable product.
Second they don't have targeted linux right away because Linux people are known to be against Microsoft so Microsoft released the mac version First.
