Please report your findings based on the Troubleshooting Guide. That error seems strange.

aombk · 2024-02-08T02:29:16Z

I am not sure what you mean by that.
inside the folder: C:\Users{USER}\AppData\Local\KeePassXC are these files:

org.keepassxc.keepassxc_browser.json
org.keepassxc.keepassxc_browser_brave.json
org.keepassxc.keepassxc_browser_chrome.json
org.keepassxc.keepassxc_browser_chromium.json
org.keepassxc.keepassxc_browser_edge.json
org.keepassxc.keepassxc_browser_firefox.json
org.keepassxc.keepassxc_browser_tor-browser.json
org.keepassxc.keepassxc_browser_vivaldi.json

all chrome based browsers work and can connect
the files:

org.keepassxc.keepassxc_browser.json
org.keepassxc.keepassxc_browser_firefox.json
org.keepassxc.keepassxc_browser_tor-browser.json

contain this:

{
    "allowed_extensions": [
        "[email protected]"
    ],
    "description": "KeePassXC integration with native messaging support",
    "name": "org.keepassxc.keepassxc_browser",
    "path": "C:\\Program Files\\KeePassXC\\keepassxc-proxy.exe",
    "type": "stdio"
}

the keepassxc-proxy.exe path is correct.

the registry contains the entries mentioned in the troubleshooter

i dont know what to do with process monitor

in firefox debugging i get these error messages:

also i dont know what to do with debugging keepassxc-browser.js in the firefox debugger

was that what you were asking for?

varjolintu · 2024-02-08T05:00:25Z

A couple of things to check:

Is the keepassxc-proxy.exe running?
What happens if you run it manually?
Have you tried to downgrade Firefox?

aombk · 2024-02-08T05:28:15Z

keepassxc-proxy.exe was running under the edge browser

if i run keepassxc-proxy.exe manually i get a blank window

and keepassxc-proxy.exe is now running under explorer.exe as well as under edge but firefox still cannot connect

no I havent tried downgrading, could try in the following days.

but why isnt it working? does it make any sense?

varjolintu · 2024-02-08T05:34:57Z

but why isnt it working? does it make any sense?

No it doesn't. This is why I suggested that you try to downgrade.

sakurawald · 2024-02-08T12:07:27Z

but why isnt it working? does it make any sense?

No it doesn't. This is why I suggested that you try to downgrade.

Please see this: #2113

aombk · 2024-02-10T13:48:47Z

ok so i tried a couple of older versions, and some portable ones, also tor browser. nothing seems to work. keepassxc-proxy.exe does not run with firefox. only with other chrome based browsers. what else can i try?

varjolintu · 2024-02-10T13:56:38Z

@aombk Can you paste the relevant registry entry here? You can also verify the path Firefox is trying to use with https://docs.microsoft.com/en-us/sysinternals/downloads/procmon

aombk · 2024-02-10T14:48:27Z

the key name is
HKEY_CURRENT_USER\SOFTWARE\Mozilla\NativeMessagingHosts\org.keepassxc.keepassxc_browser
and the value is
C:/Users/{USER}/AppData/Local/KeePassXC/org.keepassxc.keepassxc_browser.json

will check now with procmon

aombk · 2024-02-10T16:03:50Z

these are from procmon
i really dont know what to look for.

varjolintu · 2024-02-10T16:07:43Z

the key name is HKEY_CURRENT_USER\SOFTWARE\Mozilla\NativeMessagingHosts\org.keepassxc.keepassxc_browser and the value is C:/Users/{USER}/AppData/Local/KeePassXC/org.keepassxc.keepassxc_browser.json

will check now with procmon

Does this match with the registry entries with Chromium-based browsers?

aombk · 2024-02-10T16:36:52Z

yes, for edge its this:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Edge\NativeMessagingHosts\org.keepassxc.keepassxc_browser
C:/Users/{USER}/AppData/Local/KeePassXC/org.keepassxc.keepassxc_browser_edge.json

aombk · 2024-04-11T17:12:30Z

i would like to note that the issue is still not resolved

varjolintu · 2024-04-11T17:28:03Z

A couple of new points/questions:

Are you using some anti-virus or anti-malware software that could affect this?
Try disabling all other extensions and see if it solved the problem
Create a new temporary profile to Firefox and install the extension there, does it work?

aombk · 2024-04-11T19:24:47Z

I am using the microsoft windows built in security.
I disabled it and all firefox extensions and I also did a new firefox profile
but keepassXC browser plugin still could not connect to keepassxc software

varjolintu · 2024-04-12T03:47:41Z

Does re-enabling the "Update native messaging manifest files at startup" help?

aombk · 2024-04-12T09:10:21Z

I don't know where to re-enable that

varjolintu · 2024-04-12T09:53:20Z

I don't know where to re-enable that

Browser Integration -> Advaced. Accept the dialog with OK after doing that.

aombk · 2024-04-13T22:35:51Z

nope, it does not help unfortunately
