Enable or disable Tab Sleep in Firefox browser
Microsoft Edge also comes with a similar feature to enable or disable sleeping tabs and automatically suspend tabs. Those who use the Firefox browser can try this built-in option to automatically suspend Firefox tabs when not in use or disable that feature. Here are the steps: At first, open the Firefox browser using the Search box or some other way you prefer. Now access the Advanced Preferences page. For this, type about:config in the address bar, and press the Enter key. You will see a Proceed with Caution warning message. There, click on Accept the Risk and Continue button and Advanced Preferences page will open.
Now use the search box and type browser.tabs.unloadOnLowMemory. When this preference is visible, double-click on it to set its value to false.
That’s it! You have disabled the tab sleep feature in your Firefox browser. Now, whenever you are working with too many tabs and some tabs are not accessed for some minutes, then Firefox won’t suspend those idle tabs automatically. To turn on or enable tab sleep in Firefox, just follow all the above steps, and set tabs.unloadOnLowMemory preference value to true. Hope it will help. Related reads:
