Stop Chrome From Discarding Background Tabs in Memory Saver

Chrome can unload a background tab to free memory, then reload it when you click back. If that resets a form, stops a video, or costs you time, Memory Saver is usually the cause.

The fix is in Chrome's Performance settings. Keep selected sites active, choose a slower deactivation level, or turn Memory Saver off.

In this guide, I have covered:

Why Chrome Unloads Your Background Tabs

You leave a tab open, come back later, and the page reloads from the top. That is Memory Saver at work.

Chrome’s Memory Saver frees memory by unloading inactive tabs. When a tab is discarded, Chrome removes its page content from memory and reloads it when you return.

Usually you will not notice. You will notice when the page takes time to reload, a temporary state resets, or the site no longer looks ready to use.

If you want to stop Chrome from discarding tabs, the cleanest fix is to put the affected sites on Chrome’s always-active list. Google documents these controls in its guide to personalizing Chrome performance. The same Performance page holds Memory Saver, the deactivation level, and the site list.

Keep Specific Sites Active in Chrome

You have two or three sites you need open all day, but you still want Memory Saver to handle everything else. Add those sites to the always-active list.

1. Open Chrome on your computer and select the menu.
2. Select Settings.
3. Open Performance in the left sidebar.
4. Make sure Memory Saver is on.
5. Find Always keep these sites active.
6. Click Add.
7. Choose Add current sites to pick a site that is already open in a tab.
8. Tick the site you want to keep active, then click Add.

Repeat for any other site you do not want Chrome to unload. Memory Saver stays on for the rest of your tabs.

You’ll know it worked when the tab stays loaded after you switch away and come back.

Add a Website Manually

The site you want to protect is not open right now? Type its address instead. The manual option sits in the same place.

1. Open Settings, then select Performance.
2. Find Always keep these sites active and click Add.
3. Select Add sites manually.
4. Type the website address in the field.
5. Click Add to save the site to the list.

Go back to the site’s tab and switch away for a minute. If it stays loaded, the rule is working. If not, check that the address matches the one you use to open the site and that Memory Saver is on.

Adjust the Memory Saver Deactivation Level

Tabs are dropping too fast even though you have not added every site to the list? Change how quickly Memory Saver acts.

1. Open Settings and select Performance.
2. Confirm that Memory Saver is on.
3. Find the Memory Saver mode selector.
4. Choose Moderate, Balanced (recommended), or Maximum.
5. Return to your background tabs and watch what happens.

Moderate waits longer before Chrome unloads a tab. Balanced uses Chrome’s recommended timing. Maximum uses the shortest window.

TIP: Start with Moderate. It waits longer before Chrome makes tabs inactive, so you should see fewer reloads without giving up all memory savings.

You’ll know it worked when a tab that used to reload stays put after a short break.

Turn Off Memory Saver Completely

You regularly keep a dozen heavy tabs open and do not want Chrome touching any of them? Turn Memory Saver off.

1. Open the menu and select Settings.
2. Select Performance in the left sidebar.
3. Turn off the Memory Saver toggle.
4. Close and reopen the tabs that were already discarded.

This stops Chrome from unloading tabs through Memory Saver, but it also gives up the memory savings. Keep it off only if you need many complex tabs open at once.

If you turn it back on later, add your important sites to the active list first.

Use Pinning for a Quick Alternative

You need one tab to survive a short break, and you do not want to edit the Memory Saver list? Pin it.

1. Open the tab you want to protect.
2. Right-click the tab.
3. Select Pin.
4. Return later and check that the page content is still there.

Pinned tabs are already treated as active and are not deactivated in the same way as ordinary background tabs. Pinning changes how the tab is organized, so use the site list for a permanent solution.

Chrome also avoids discarding tabs when they are playing audio or video, sharing your screen, showing notifications, downloading files, or holding a half-finished form.

Advanced Site Matching Rules

You are adding a site manually and Chrome asks for a pattern, not just a plain address? The format is [scheme://][.]host[:port][/path][@query].

A plain domain such as example.com matches that domain and its subdomains. A leading dot, such as .example.com, matches that domain only.

You can restrict a rule to a path, such as www.example.com/finance, or use a wildcard in a query, such as youtube.com/watch?v=*. Wildcards in the host prefix, suffix, or substring positions are not supported. For example, example.com/* does not work as a path wildcard.

If you are unsure, start with the plain domain and test it before adding more rules.

Check Whether a Tab Was Actually Discarded

A page looks stale and you are not sure whether Chrome unloaded it? Chrome has a diagnostics page for that.

1. Open a new tab in Chrome.
2. Type chrome://discards in the address bar.
3. Press Enter.
4. Review the list of discarded tabs and their status.

Use this page for troubleshooting. It does not replace the Performance settings. If a tab shows as discarded, add its site to the active list or slow down Memory Saver.

Chrome does not offer the same Memory Saver personalization controls on iOS or Android. On mobile, the available memory-management behavior is not customized through the desktop Performance settings described here.
