Cannot connect to KeeWeb / Firefox #28

Jobode · 2021-08-30T13:09:26Z

I installed the KeeWeb app and turned on Firefox browser integration under the Browser settings. Then installed the keeweb addon under Firefox.
Under connection then the option "using the native app" brings me the error message:
Cannot connect to KeeWeb, please check if KeeWeb is open and browser integration is enabled in settings. (it is...)
Other addons like floccus or ublock work fine.
What could be the error? The "web-only" connection works.

I use Firefox 91.0.2 (64) on Windows 10 / KeeWeb v.1.18.7

Seems like I have a similar problem, maybe the same:
I run KeeWeb, then Firefox, when trying to use KeeWeb:

Jobode · 2021-08-30T17:52:32Z

ok, very strange actually: I just did exactly the same installation on my notebook at home, and here it runs without problems.
I'll do another installation on my desktop PC later. Let's see if it works there too.

Can console data from Firefox be helpful to find out why it works on one computer and not on the other?

Jobode · 2021-08-30T21:18:19Z

I think I have found the problem.
The problem occurs when you want to install KeeWeb and KeeWeb Connect on a multi-user Windows system.
On my notebook there is only one user with the typical administrator account. There everything works.

However, when I try to install KeeWeb on Windows 10 as a default user, I get this error message:

So then you normally install the program with the right mouse button -> context menu -> run as administrator.
That works so far.
But if you start KeeWeb and activate the browser integration and install the KeeWeb Connect Plugin under Firefox, the file "native-messaging-kwc.firefox.json" is created under the admin account (->User ->AppData->Roaming->KeeWeb) and NOT as it should be under the default user "Jo" (->User->Jo->AppData->Roaming->KeeWeb).

So the installation routines from KeeWeb are probably not programmed very well?
As a workaround, you can make the Windows default user to a user with administrator rights for a short time and then install KeeWeb and the Firefox plugin. However, after configuration the connection does not work until you restart KeeWeb.
Probably a important thing too is to remove all program residues before reinstalling, also the KeeWeb directory under User -> Appdata -> Roaming-> KeeWeb for the standard user and the admin user.
When everything is set up and working, you can change the user back to a standard user.

zbyna · 2021-08-31T11:20:32Z

OK. I will check on my Linux installation. I am out of my computer now.

zbyna · 2021-08-31T19:59:32Z

My issue seems to be different:

I am using KeeWeb in AppImage format, it means that every single launch extract application to unique path in tmp directory
there is a file /home/zbyna/.mozilla/native-messaging-hosts/net.antelle.keeweb.keeweb_connect.json which contains the path to the keeweb-native-messaging-host
turning off and on of the checkbox in Settings / Browser / Firefox will update path to keeweb-native-messaging-host in net.antelle.keeweb.keeweb_connect.json, and then it works well

Firefox console log before re-enabling checkbox:

21:12:20.202 File at path "/tmp/.mount_KeeWeb1bsF11/keeweb-native-messaging-host" does not exist, or is not executable 2 Subprocess.jsm:152

Xenion1987 · 2021-09-02T20:47:55Z

I had the same issue:

Installed Windows an a new Device
Installed my common stuff (KeeWeb is part of that)
Trying to log into a website and got the same error message @zbyna showed in the first screenshot

After reading your comments, I took a look at the process list in the taskmanager and could not find the application keeweb-native-messaging-host.exe. So i tried to exdecute it manually and got an error message, that VCRUNTIME140.dll was missing.

After installing the related C++ runtime and a reboot, it worked as expected.

Where to download:
support.microsoft.com

EDIT:
I had the same issue on Chrome and Edge. Installing the C++ runtime fixed it for all browsers. So this issue is not related to Firefox only.

Windows version:

PS > [environment]::OSVersion.Version
Major  Minor  Build  Revision
-----  -----  -----  --------

Firefox: 91.0.2 (64-Bit)

KeeWeb Connect: 0.3.7

Jobode · 2021-09-03T14:46:15Z

I can confirm this additional solution.
I have tried this on another Windows multi-user system.
It is interesting that my first solution of changing user rights works without installing the C++ runtime.
But your solution is certainly much simpler. Thank you very much.

antelle · 2021-09-08T17:16:22Z

Hi!
@Jobode did you also run KeeWeb as Administrator (or just installed as Administrator and ran as a regular user)? It you run it as your regular user and then check the Firefox checkbox, does it create the manifest?

@zbyna, I had this exact same issue while using both AppImage and Linux.x64 releases, needing to recheck the browser integration box every launch.
I "fixed" this by just running KWC myself whenever I start Keeweb. You can get it by downloading the linux.x64 release rather than the appimage.

keeweb-native-messaging-host /home/<username>/.mozilla/native-messaging-hosts/net.antelle.keeweb.keeweb_connect.json [email protected]

I added that to my own .Desktop, and it appears to work great. The KWC process even dies when keeweb is closed
