My Task manager shows 6 firefox.exe, what should I do?
My computer is running slow, so I went to Task Manager, and discovered 6 Firefox.exe listed. Why would that be? should I get rid of some of them?

More than one process is normal for the current Firefox. http://www.ghacks.net/2016/07/22/multi-process-firefox/
Multi-process Firefox is codenamed "e10s". https://wiki.mozilla.org/Firefox/multiprocess
Try to disable multi-process tabs in Firefox. You can disable multi-process tabs in Firefox by setting the related prefs to false on the about:config page.
browser.tabs.remote.autostart = false browser.tabs.remote.autostart.2 = false
Type about:config<enter> in the address bar. If a warning screen comes up, press the I Accept the Risk button. At the top of the screen is a search bar.
You can first try to limit the number of content processes to 1.
You may see three or more Firefox processes running.
- one process for the main Firefox thread (user interface)
- one or more content processes set via dom.ipc.processCount
Options/Preferences -> General -> Performance
remove checkmark: [ ] "Use recommended performance settings" - one process for the compositor thread (Windows;graphics)
You can find the current multi-process state on the Troubleshooting Information (about:support) page.
