nsAppShell:eventwindow is supposedly a firefox program; it is killing my computer speed... takes over. How to get rid of it (task master wouldn't allow me to end program, etc.). Thanks!

This is possibly caused by the multi-process feature that is enabled in the current Firefox release.

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

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.
