The Memory Saver Problem
Modern web browsers consume a massive amount of system memory (RAM). To prevent Google Chrome from slowing down your computer, Google introduced a feature called “Memory Saver.” When you have many tabs open, Chrome will quietly “sleep” or suspend the tabs you haven’t looked at in a while. When you click back to a suspended tab, it instantly reloads. While this is great for system performance, it can be infuriating if you are in the middle of filling out a long web form, monitoring a live dashboard, or reading an article offline, only to have the tab refresh and lose your place (or data) because Chrome put it to sleep.
How to Disable Memory Saver Globally
If you have plenty of RAM (e.g., 16GB or 32GB) and you never want Chrome to unload your tabs automatically, you can turn off the Memory Saver feature entirely.
1. Open Google Chrome and click the three vertical dots in the top-right corner of the browser.
2. Select Settings from the drop-down menu.
3. In the left-hand navigation sidebar, click on Performance.
4. At the top of the Performance page, look for the section titled Memory Saver.
5. Click the toggle switch next to “Memory Saver” to turn it Off (it will turn grey).
Once this is disabled, Chrome will keep every single tab loaded into your active RAM until you manually close them.
How to Whitelist Specific Websites
If you like the idea of saving RAM but you have a few specific web apps (like a company portal, a spreadsheet, or a live chat tool) that you never want to reload, you can create exceptions.
Leave the main “Memory Saver” toggle turned ON. Directly below it, look for the section labelled Always keep these sites active. Click the Add button. You can then type in the URL of the website (e.g., `app.slack.com` or `docs.google.com`). Chrome will aggressively sleep background tabs to save memory, but it will permanently exempt the specific URLs you added to this whitelist.
