<![CDATA[Configuring firewall for Opera]]>Hello,

I really love Opera browser except 4 important problems, 2 of them connected with Firewall I post here.

  1. I have 3 browsers - Opera, Firefox, Edge. Also I prefer to block at Windows Firewall all inbound and all outbound traffic by default, except individual enabling rules. When I setup firewall as I need - Edge works with only 1 allow rule, Firefox works with only 1 allow rule, but Opera don't work even with allow rules for all *.exe from Opera folder! Please, tell which exactly firewall rules your Opera needs to work through "block all by default" Firewall?

  2. It's very annoying to use Opera with Firewall because only Opera (not one of Firefox/Chrome/Edge/etc) after each update changes it's main folder and thus path to a main opera.exe. You must resolve this problem by using folders with version as backup, but use current active version from one constant folder like "Active" or "Current" thus it's path will not change after each update!

Waiting for your help with #1!

I cannot test your suggestion atm, because in between I found a workaround:
Testing TinyWall now.
With that little Firewall-"Extension" you could simply add relevant exe to your whitelist. Let's see how occuring Opera-Updates get affected or simply work... but you have another two tasks running in background. More Benefits it helps to look up processes and where they want to talk to which ip-addresses and even restrict LAN-Connections.

Yes, you would have to change the path everytime an update was installed.
The wrong path that is generated during installation seems to be a place holder for future healing...

I hope to find a workaround soon or I have to leave Opera. I don't accept that every program is sending out information from my computer, when your personal data is your greatest worth these days.

"C:\WINDOWS\ServiceProfiles\LocalService

Those are problem something the Opera installer adds. Not sure. I guess you can't modify them.

I set the Windows Firewall to block outgoing connections by default. The rule I had to add to allow Opera's outgoing connections was a program rule for "C:\Users\yourusername\AppData\Local\Programs\Opera\92.0.4561.21\opera.exe". I named the rule "My Opera Rule Versioned opera.exe". I tried adding rules for "C:\Users\yourusername\AppData\Local\Programs\Opera\opera.exe" and "C:\Users\yourusername\AppData\Local\Programs\Opera\launcher.exe", but unfortunately, those didn't help. 😞

So, yeah, the rule needs to be changed with each update of Opera in that case unfortunately.

  • I added both programs (launcher.exe and opera.exe) to the app exeption list as well to allow communication through Windows Defender Firewall:

    • Bild Text

    While adding my entries they were automatically called "Opera Internet Browser" point to:
    C:\Users\myuser\AppData\Local\Programs\Opera\launcher.exe
    C:\Users\myuser\AppData\Local\Programs\Opera\opera.exe

    1. There were already two entries called "Opera" they had these paths:
      C:\WINDOWS\ServiceProfiles\LocalService\AppData\Local\Programs\Opera\launcher.exe
      C:\WINDOWS\ServiceProfiles\LocalService\AppData\Local\Programs\Opera\opera.exe

    When I try to enter the path from already present entries to an outgoing rule I get an error message:

    "The file "C:\WINDOWS\ServiceProfiles\LocalService\AppData\Local\Programs\Opera" was not found. Check the spelling and try again."

    Obviously it does not find the path.

    Please check this image wether you can find anything wrong: Bild Text
    The image shows outgoing rules for the private profile of this computer, that is currently used by this computer.
    I'm not sure if the path is correct, but it's the path the icon points to:
    C:\Users\myuser\AppData\Local\Programs\Opera\launcher.exe

    Firewall rule setup made this out of it automatically:
    %USERPROFILE%\AppData\Local\Programs\Opera\launcher.exe

    I added the same path with opera.exe.
    Both with TCP and UDP entries.

    Outgoing connections are blocked:
    Bild Text

    Now, i'd need more help, because it's weird bahavior.
    Either the path is wrong or something else blocks at Operas side?

    The language in images is german, if there are questions....

    Who knows what?

Windows Firewall is configured to block inbound and outbound traffic, but traffic is allowed when a rule is defined.

    Created 2 rules for launcher.exe / TCP and UDP.
    Created 2 rules for opera.exe / TCP and UDP.
    All for "private" network (not for public or domain) makes 4 rules for Incoming and 4 rules for outgoing traffic only for Opera browser, but not getting content in browser when calling a website.

    What am I doing wrong?
