Mozilla Firefox is an open-source free web browser that is used millions of people. Mozilla Firefox may not even come close to Chrome’s user base, but it still has its own loyal users who are more than happy to stick with Firefox.
However, Mozilla is not immune to bugs and issues. One issue that is repeatedly reported by Firefox users is that there are multiple Firefox processes running in the background. Because of this the browser reportedly becomes slow and even crashes. In this article, I have discussed how to make Firefox disable multi processes running in the background.
Why Does Firefox Have So Many Processes?
The reason so many processes run for a single window in Firefox is that it enhances the web performance significantly. But the web performance won’t matter to the users if the browser doesn’t work in the first place. Try to disable Firefox multi-process, which has been reported to be the main fix for this issue.
How To Check If Multiple Processes Of Firefox Is Running?
If your Firefox has become slow and you are unsure whether multiple processes of Firefox running in the background is causing this issue, then you can check it in the Task Manager. To use the task manager, follow the steps given below:
- Press the Ctrl + Shift + Esc keys to open the Task Manager.
- Select the Processes tab and see how many Firefox processes are running in the background.
If you see Firefox running multiple processes, then that’s what is creating those issues for you.
How To Disable Multiple Firefox Processes?
Now that you have seen Firefox running multiple processes in the background, you can try to disable it and see if that fixes the issue. Below, we have given 2 methods that you can use to disable multiple processes of Firefox.
Method 1: Change The Content Process Limit
By changing the Content Process Limit of Firefox, you can decide how many Firefox process should run in the background. To change the Content Process Limit, follow the steps given below:
- Open Firefox and click on the Options button (gear icon) on the upper right side of the screen.
- After opening the Options console, you will see a search bar on the upper side of the screen. Type hardware acceleration in the search bar.
- The search result will be on your screen instantly.
- In the Performance section, uncheck the Use recommended performance settings box. This will open options below it.
- In the content process limit section, click on the drop-down menu and select the number of processes Firefox could open in the background.
- After that close the Firefox.
Now, check if the Firefox disabled multi processes or not.
Method 2: Disable Config Value
You can also use this method to disable Firefox multi-process. To do it, follow the steps given below:
- Launch Firefox.
- Type about:config in the address bar and press Enter.
- Click on the Accept the Risk and Continue option.
- In the about config search bar, type browser.tabs.remote.autostart.
- When the config value appears on your screen, change it to False by clicking on the button next to it.
Now, check in the Task Manager if Firefox multiple processes are still running. After disabling config value, Firefox should disable multiple processes from running in the background.
So, there you have it. Now you know how to disable multiple Firefox processes running in the background. If you have any questions related to this issue, ask them in the comment section.
