To turn off Chrome's page preloading function, you can do it by: 1. Disable the Prerender option in chrome://flags to prevent preloading during hovering; 2. Turn off "predictive network behavior" in settings to reduce automatic loading requests; 3. Use extensions such as uBlock Origin for granular control; 4. Disable cache temporarily in developer tools and limit network speed to assist debugging. These methods can be flexibly selected according to different needs, and are simple and effective in operation.
Chrome's preloading feature does improve web page opening speeds, but sometimes it can affect your browsing experience, especially when monitoring the network, debugging page behavior, or saving traffic. If you want to turn off Chrome's page preloading function, it can actually be achieved through several settings and strategies.
Several ways to turn off preloading
1. Disable pre-rendering (Prerender) function
Chrome will pre-render the page you may visit in some cases, such as before clicking a link from the search results, it already loads the target page in the background. To turn off this feature:
- Enter in the address bar:
chrome://flags/#prerender2 - Find the item "Prerender pages when the user hovers over suggested URLs in Omnibox"
- Change the drop-down menu to Disabled
This will prevent Chrome from preloading the page when you hover the suggested link.
2. Turn off the “Predictive Network Behavior” option
Chrome enables predictive network actions by default, including DNS pre-resolution, TCP pre-connection, etc., which can indirectly cause the page to be loaded in advance.
The operation steps are as follows:
- Open Settings → Privacy & Security → Settings → Privacy & Security
- Click "Website Settings" under "Privacy and Security"
- Scroll to the bottom to find the option "Use prediction services to speed up web page loading" or similar name
- Uncheck
This step can effectively reduce the preload requests automatically initiated by the browser.
3. Use extensions to control preload behavior
If you need to have more granular control over which websites can be preloaded, or want to temporarily close all preload behavior, consider using some extensions, such as:
- uBlock Origin (block preload requests through custom rules)
- Lightbeam or other privacy plug-ins can also limit the browser's predictive behavior.
This method is suitable for users with a certain technical foundation and can flexibly configure it according to their needs.
4. Network settings in the developer tool (suitable for debugging scenarios)
If you are debugging web page performance and do not want the page to be preloaded to affect the test results, you can temporarily turn off the cache in the developer tool and limit network behavior:
- Open DevTools (F12 or right-click to check)
- Switch to Network tab
- Check "Disable cache"
- At the same time, you can check "Throttle" to limit network speed and avoid quickly loading and confusing test results.
This method does not permanently close preloading, but is helpful for development debugging.
Overall, Chrome offers several different ways to control the behavior of page preloading. You can choose whether to completely close or partially restrict it according to your usage scenarios, or to manage it in a refined manner through plug-ins. These settings are not complicated to change, but they are easily overlooked.
