How do I stop my web browser from using all my computer's memory?

You'll be able to: Enable Memory Saver and tab sleeping in Chrome and Edge to free up gigabytes of RAM and speed up your PC

The steps

1. 1

   Open your web browser (such as Google Chrome or Microsoft Edge) and click the three dots menu (... or ⋮) in the top-right corner. The main browser menu opens on your screen.

2. 2

   Click Settings, then click Performance (or System and performance in Edge) in the left sidebar. The browser performance settings screen opens with Memory Saver controls.

   Why do browsers consume so much memory?

   Every open tab runs its own background processes, media players, scripts, and cached pages. Leaving dozens of tabs open locks up memory that other applications need.

3. 3

   Turn the toggle for Memory Saver (or Efficiency mode in Edge) to On. The toggle turns blue and displays active memory optimization.

4. 4

   Select Balanced or Maximum mode to specify how quickly inactive tabs should release their memory. Inactive tabs are put to sleep automatically, freeing up memory until you click back onto them.
