Which features is Windows 10 Defender Firewall blocking that Opera wants to do?

@opedara Windows Defender firewall usually only blocks/asks about incoming connections. Don't know if there is some kind of log in Windows Defender firewall showing more details of the blocked connection.

Not sure. It might be the updater. But, it does say "opera.exe", so not sure. It could be a messenger app in the sidebar if you ever activated one of them.

For my Windows Defender, I see incoming rules to allow mDNS on UDP port 5353 for Opera.

I've had this happening since switching to Opera Portable.
I'm pretty sure it seems to happen (again) after every Windows 10 update, even minor ones, & I suspect it is Microsoft removing 'non-microsoft' firewall rules as I get the same when I use Chrome Portable for the first time after an update.
What we need is a read only flag in the firewall rules so we can lock a rule on and it can't be reset.
All down to MS arrogance, they know best!!!

@opedara I have the same problem, did you find a solution? I have disabled the firewall, uninstalled and reinstalled Windows, this has been going on for 3 months with Chrome and Opera, I have no problems with Edge or IE. I think Windows is blocking the computer from accessing other browsers.

@sgunhouse Yes each time it appears, that is about twice every three weeks.. Normally it appears after each of the innumerable WIN10 update patches

@sgunhouse No I just closed the browser cos probably both answers would be risky

@dugglebb That dialog should appear after an Opera update because for the firewall it's another program/executable running.

@leocg yet it doesnt happen with other browsers
so I dunno
is it just defender trying to freak users of other browsers out ?

@ceedee Because in other browsers the executable doesn't change after an update.

@leocg That makes sense...but...why does opera do it that way? Seems like a poor choice in terms of keeping customers happy...I am sure there is some technical reason for it....but if other browsers can do it, why not opera...

Same with forced windows 10 updates/reboots...sure there's a reason for it...but whats worse...a virus or pain in the ass risk of lost work first Tuesday of every month..... for mine...I choose a virus

@careware The way Opera works allows to keep the previous build and revert to it in case of an update issue.

Some people don't like it because they need to allow Opera on firewall after every update.

@leocg Thanks Leocg, makes sense I suppose.... I sit in the don't like it camp. IMO it's a bad choice by opera. I've never had to roll back from an update, but this...is a pain.... most users don't even know what a firewall is let alone why this would be happening... I guess it is what it is... one has to deal with it...

This coupled with the sidebar reappearing problem, sigh...computers suck...

@careware Maybe you never had to rollback to a previous build, but Opera may have had to do it.

Those who don't know what a firewall is would find the dialog strange on any browser.

That's true, I haven't used any other browser for 10 years. but reputedly it doesn't happen with other browsers?

I dunno, just seems something you'd want to avoid foisting on users if you were intent on gaining market share. I don't run the joint so... it is what it is

@careware Yes, the dialog will show up in other browsers if you use them long enough and visit any site that triggers it but it will only happen once.

I'm not seeing the answer to the most important question here...

What is Opera trying to do through the port that Windows Firewall is blocking? This is a question that Opera people should be able to answer more than Microsoft people, because Microsoft didn't write Opera.

The firewall appears to be doing its job; blocking a port by default then prompting me to OK or Cancel Opera from using that port that it normally blocks.

In order for me to know if I should allow Opera through that port on Private Networks, I want to know what Opera is trying to do over that port when I get the prompt. I'm not seeing an answer to that yet.
