Firefox extension issue

Hi all,
i’ve an issue, sometimes i’ve this error:

Invoke InitiAllApplications workflow: Impossible communicate with firefox extension, and i need to reinstall the extension manually. It happened once a week.

The second question is: I have some problem with click image if i run the BOT via orchestrator via another machine in citrix, no error if the source is AGENT and i run it directly into the virtual machine with the tray, any possible solution?

Thx

up please
