Version Information Please complete the following information:

Additional Context I contacted moziila's dev team about this and I got to know that "The log shows that SEB tries to restart the killed process, but restarting the Firefox content/tab process externally is not possible. SEB should be updated or configured to not kill plugin-container. Firefox works differently than Safari with respect to networking processes. If we can learn about how SEB works or how it can be configured, we might be able to avoid this." Is this something, which will be handled from seb' end or from mozilla end?

SEB needs to kill the process plugin-container to prevent screen sharing or video conferencing to be used with Firefox. The other option is to kill Firefox completely. I didn't prefer this originally, because users might loose open tabs or data entered in open webpages.

If Mozilla has another idea how SEB could stop users from using video/audio conferencing and screen sharing in Firefox while SEB is running, I would be happy for any input.
