The main topic should provide links to portable versions , but I think I was asking for that one for a year now...
Canary_Channel From Chrome-bin you get 80.0.346.0 Folder msedge.exe msedge_proxy.exe Click on msedge.exe & the Edge Browser will open with ver. 80.0.346.0 without being installed on your PC. However it will not auto update. It is a fully working Browser.
That's not how it works. When you close the Browser, you have to reinstall Browser from msedge.exe Every Time.
I have fixed as into the past with target: "C:\Program Files\Microsoft\Edge Beta\Application\msedge.exe" --ignore-certificate-errors but this is not good
It could be helpful with more info ? Are you talking Canary_Channel, Dev_Channel, Beta_Channel ? Latest Build ?
I expect SmartScreen or any of Windows Defender related security mechanism. Because it takes time to scan and analyze it.
