Microsoft Edge Browser Delayed Opening

[gonzohimer]

Microsoft Edge (v111.01661.44 & newer) will not immediately open & displays a white screen for up to 60 seconds then opens or then it may display a connection has been interrupted refresh page, & finally load. Older versions of Edge (approx. v90 to 100) have been proven to work fine. Turning off all Avast components with the exception of the firewall makes no difference. Turn off the firewall & Edge works fine. All firewall rules for Edge browser are in place allowing internet access. I tried to do a Remote View with Avast Tech Support but while the remote connection was enabled Edge would not fail. I have the same basic installation of W11 and Avast on 3 more computers that work fine. Bottom line there seems to be a compatibility issue between the newer versions of Microsoft Edge and the recent versions of Avast Premium Security.   HP ProBook 650 Laptop, older and & new installs Microsoft Windows 11 Pro Version 21H2 22000.1696 updated, Avast Premium Security (build 23.2.7961.780) updated.

Has anyone else experienced this? Any suggestions how to fix the problem?

Hi,

what happens if you choose firewall setting 'Smart Mode'?
See here:

Because it seems there is a malfunction in Avast firewall.
If I choose mode 'Ask' Avast blocks Edge, even there are firewall rules that allow Edge internet connection.

dnzrzx34: When using Allow or Smart Mode - Edge will work normally for me. The Ask mode will about 90% of the time cause the long delay.

This updated post hopefully will benefit other forum members who may run into an issue like this. In this case Avast Firewall settings & Microsoft Edge browser have compatibility issues - at least on my particular Laptop. I was hoping for a permanent fix but with the constant Microsoft Edge updates happening 3 or 4 times a week I cannot get the browser to consistently open properly and still retain control of what programs are "requesting" access the internet. Because Avast Premium seems to work very well on 3 other computers I have decided to ditch the Edge browser and move on to another even though there were a lot of things I liked about it.

You need to reset all your rules if you want to use ASK mode... then it works, but you need to confirm/decline everything again, so there will be a lot of alerts...

EDIT: This helped me only until restart... after restart firewall in ASK mode is still blocking Edge and it's not showing any prompt... just blocking it...

AVAST TEAM we need a fix ASAP please!

It seems MS Edge processes won't close when Avast firewall is in ASK mode, you have to use Windows task manager.
