How can I limit the amount of memory used by Firefox?
Firefox on Windows 10 uses too much memory, >1G. Task Manager shows >7 Firefox processes. The sound gets distorted. What should I do?

Hi Neiljacobson,
Unfortunately, I'm unaware of a way to set a hard limit for how much memory Firefox uses. This article might help you reduce the amount it is using:

Another method you can try is to head to about:memory and click on Minimize memory usage under the Free Memory tab.
Hi neiljacobson, Occasionally, I have audio issues, also. (It's the OEM.)
Open Windows Task Manager. Select the Services tab. Find audiosrv, right-click on it and select Restart.
As far as the memory usage is concerned, @cor-el, one of the moderators here, offers this explanation:
It is quite normal to see more Firefox processes running.
- one process for the main Firefox thread (user interface) - one or more content processes (default is 8), see: Options/Preferences -> General -> Performance remove checkmark: [ ] "Use recommended performance settings" - one process for the compositor thread - one process for the WebRender when this feature is enabled
You can find the current multi-process state on the Troubleshooting Information page (about:support).
"Help -> Troubleshooting Information" -> "Application Basics": Multiprocess Windows Remote Processes
See also the Remote Processes section further down for more detail.
