Firefox is one of the most popular browsers today, but even this stable, user-friendly browser could cause some problems. After some time, Firefox could start to take more memory than it should, but we’ll tell you how to solve this problem. Making sure your browser is up to date and disabling the plugins seems helpful. This article compiled a list of solutions to help you fix Firefox’s high memory usage in Windows 10.

Why is Firefox taking up so much memory?

Sometimes the issue is with an old or outdated internet browser. You should update your browser immediately if it has not been updated.  The problem is often brought on by faulty data or excessive caching. However, add-ons and specific browser settings also influence Firefox’s behavior on your system. Changing the theme might potentially result in Firefox consuming too much RAM, in addition to several other issues we will cover in the following section. How much RAM should Firefox use? It is impossible to put a cap on RAM use since it will depend on what activities are carried out on a browser. Suppose all you do with your browser is read articles on the web. In that case, you will be using minimal RAM as opposed to if you are streaming videos, playing graphic-intensive games, performing online video edits, etc. In fact, many users have complained of a Firefox YouTube memory leak. You should, however, regularly consult your Task Manager to know when there are abnormal changes or spikes in RAM use.

How do I turn off multiple processes in Firefox?

1. Switch to another browser

Millions of people worldwide chose Opera for its speed, privacy, and the new features that allow them to work and browse faster and more efficiently. With this browser, you do get more time and speed by being able to organize your tabs and workspace in a manner that is not even more time-consuming. You can switch to Opera fast; the download takes only a couple of seconds, and you’ll have the browser installed on your device in no time. Using Opera’s unique functionality, you can automatically import all your browser info, install Chrome extensions and begin browsing immediately. The more tabs you open in your browser, the less memory is available. With Opera’s Workspaces functionality, you can organize your tabs based on interests or personal/professional search. It’s only up to you which categories you want to create. Workspaces will allow you to navigate smoothly through your browsing history, find faster what you are looking for, and save more memory by closing all the other tabs you don’t need.

2. Update Firefox

Once you notice a Firefox memory leak, an update should be your first resolution attempt.

3. Disable your plugins

You can also disable or delete some unnecessary plugins and add-ones because they also could use a lot of memory. Disabling unnecessary add-ons and plugins proved to be the best guard against a Firefox memory leak. But, of course, if it turns out that you need some of the disabled add-ons, you can always re-enable them.

4. Check Firefox preferences

You can reduce Firefox memory usage by tweaking the about:config settings.

5. Use fewer tabs

Most Firefox users open only a few browsers at the same time. However, having around 100 tabs open at once may trigger a Firefox memory leak. Try to close the tabs that you’re not using actively.

6. Use the Minimize memory usage button
