Disable plugin-container.exe in Firefox

Starting from the version 3.64, Mozilla Firefox starts a separate process for plugins like Adobe Flash, Adobe Air etc. so that if these plugins crash they crash in a separate process. This avoids the main browser process not to crash along with the plugins. The separate process is started using the binary file plugin-container.exe. If you do not like the idea, you can stop this. Here is how :

  1. Open your Firefox browser.
  2. Type about:config in the location bar and press Enter.
  3. Click on the button I’ll be careful, I promise to proceed

  4. In the Filter text box type dom.ipc, you would find six entries as shown :

  5. Double-click on all the entries with values true to change their values to false. It would look like this :

  6. You can close the settings tab now. Now the plugin-container.exe is disabled and Firefox will use the plug-ins in the old fashion.
