Rx 9.1.0/9.1.1: Firefox Extension not working

[dugovic.milan]

Hi, our Ranorex 9.1.x is likely not communicating properly with FF Extension and for that reason FF became a "no go" for us

ERROR: "Ranorex technology limitation"



I already tried to (none of this worked):

- Reinstall the extension
- Install the extension via file
- Make several tests with FF 67.0.4, 68.0.1
- Install FF first --> Restart --> Install RxStudio
- Install RxStudio first --> Restart --> Install FF
- Check for any error in Event Viewer (Event Log)
- Check the ongoing pipe connection Rx <--> FF Addon via PowerShell (FF is missing, only Chrome is working properly)

Code: Select all

[System.IO.Directory]::GetFiles("\\.\\pipe\\") -match 'Rx9*' 

- Check processes via Task Manager for MsgHost, which should also be responsible for Rx <--> FF Addon communication



- Check registries:

Code: Select all

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Mozilla\NativeMessagingHosts\com.ranorex.msghost
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla\NativeMessagingHosts\com.ranorex.msghost
Computer\HKEY_CURRENT_USER\Software\Mozilla\NativeMessagingHosts\com.ranorex.msghost

NOTE: After multiple tries, the registries "com.ranorex.msghost" from HKLM were saved with following value for some (unknown) reason, but this can be easily fixed by deleting "Runtime\"

Code: Select all

C:\Program Files (x86)\Ranorex\Studio\Bin\Runtime\Ranorex.Plugin.FirefoxMsgHost.json

Anyone having the same issue? Anyone with an idea, how to solve this?

Hello dugovic.milan,

It appears you have already tried several troubleshooting steps, I am curious if you open firefox and view the extensions do you see the Ranorex extension? if so can you provide a screenshot? This will tell us if the Extension is being installed at all.

Regards,
Sean

Hello Ranorex Support,

I already opened a ticket for this issue and had 2 remote sessions, but to answer your question...

Yes, Ranorex Addon is present at all times. The problem is, that Addon itself is not able to start any executable, hence it won't start MsgHost as well. We tried to debug the Addon and manipulate/exchange the path for different executable, but unfortunately without any success.
