@opedara I would agree this thread is weird...
The bottom line is, it's gonna take a fair bit of effort to figure out. You have to decide if that energy exceeds moving to a different browser.
Personally, I am just ignoring the issue until I can summon the energy to make the move...I find it a bit strange that Opera seem to design their browser this way... from a customers perspective, it's best not to have to exert energy...

What way?
In such a way as to cause a pop up? Like...described in this thread... you seem to think it's not by design...you could be right...I don't know...
I don't know what the real cause is, seems as tho nobody in this thread does.... one suggestion is because opera's executable is getting replaced on updates...
That doesn't help me.....I dunno man... all I can tell you is it doesn't happen with other browsers...one can only presume it's something opera is doing that the other browsers aren't...
Maybe, maybe not,Do you work for Opera or are you just a hobby moderator? Where I stand it's easier to swap browsers than try and find out what the issue is... that's why I find it a bit strange, because it doesn't bode well for Opera... but who the hell knows...im a consumer, they're always ignorant fools

@careware No, I don't work for Opera.
As already said in this topic, the only way to know what incoming connection triggers the firewall pop-up would be to keep monitoring the network traffic. And that would tell only the one that caused that pop-up.
And yes, you may see the firewall pop-up again after each update because opera changes the path to the opera.exe executable file.

Let me try to organize things a little bit.
Why do I have to authorize incoming connections to Opera, in Windows Firewall, (almost) every time after each update?
That's because the path to opera.exe changes on every update and that makes the firewall thinks that it's dealing with a different program
What are those incoming connections that triggers the firewall alert pop-up?
That is yet to be determinate and can be a lot of things. And it's something normal. needed for web to work.

We need some URLs where this is triggered for everyone so we can check things out on a page-by-page basis. It's "URL, or it didn't happen".

@burnout426 It happens for me most of the times I launch opera. The start website is ebay. It does not happen every single time. This occurs I think on two computers. The site is allowed in windows firewall.

Sorry, incoming connections to web browsers are in no way normal and are not needed for web to work.
It could be possible (although not likely) that some Opera components connect to each other - I have seen such behavior in some programs; this would be legitimate behavior, able to trigger firewall notificatons.
All my Opera instances sit behind NAT or similar devices (eg home routers) and incoming connections are plain impossible - everything is working without them nicely. No firewall prompts either.

Ebay does indeed trigger it for me in Chrome, Vivaldi and Opera. I can make them both not trigger it if I enable Opera's adblocker and tracking protection and have uBlock Origin enabled in Chrome. I'm looking at the net log for Opera to try and find out what tracking/ad site URL Ebay loads that triggers it. But, I haven't had any luck yet.
I can't seem to get Firefox to trigger it, even with all tracking protection off.

Are you behind some kind of router or directly connected to net?
You can look at connections in cmd prompt (netstat -anband/ornetstat -anb) - if you are able to parse that output -

@burnout426 Here Ebay triggered the firewall dialog on Vivaldi but not on Chrome Canary.
And later I went to Ebay again, after have cleaned the rule on the firewall, and that time it didn't trigger the incoming connection pop-up. -

Well, after some googling it looks like not incoming connection from outside world, but mDNS service (UDP 5353), allowing to discover some kind of devices (like network printers and chromecast) in your local network. I have not found any other explanation yet. Why ebay does trigger it - no idea.
In Chrome this can be switced off by disabling setting "Show notifications when new printers are detected on the network".
Opera seems not to include any mDNS (also called Avahi, ZeroConf, Bonjour) related settings or flags.Edit: This behavior can be related to some kind of notifications. I have (desktop) notications disabled here and no firewall prompts; in other place I did enable notifications (to see MS Teams activity) and I recall that I have seen there some firewall prompts afterwards. I correlated them with switching between various VPN networks, but actually they could be have triggered by (first) notifications (after Opera update) also.

Hi,
I found this discussion while searching for an answer to the same "problem". On my pc, this warning Only pops up while clicking on my LinkedIn bookmark. However, it doesn't pop up every time I go to LinkedIn, perhaps a couple of times per month. Have not yet tried any of the suggestions mentioned here. -

The warning comes up for me when first using the Discord web page app to video chat (if there aren't any entries in the firewall rules for that Opera already). In this specific case, I'm sure it's for WebRTC.

@jhl As expected.
I'm hoping everyone realizes that this is not a good thing, completely unnecessary, and should never happen.
The user can't see what exactly it's trying to access, and shouldn't have to go through a long technical forum thread to try to understand it or resolve it.
No other apps I open do this. It's a security concern. Opera developers need to fix it. We shouldn't have concern randomly opening the app that it needs a firewall port opened for some unspecified reason.
