Key notes
Tor browser has been around for a long time and has been used by millions of people all over the world. However, it has some issues that users may encounter from time to time. Sometimes, you may havetrouble installing the Tor browserbut we have a guide for the same.
One common issue with Tor browser is high CPU usage. Many users have reported that their CPU usage goes up to 100% when they use this application.
This can be very frustrating especially if you have an older PC or laptop which doesn’t have powerful CPUs like those found in modern laptops and desktops.
Why is Tor browser using so much CPU?
If you are using the Tor browser, you may notice that it uses a lot more CPU than other browsers. The reason is that it has to do more work than other browsers in order to protect your privacy.
Some of the common reasons why it uses so much CPU include:
Can I limit Tor browser’s CPU usage?Yes. You can close all other applications that may be running in the background. These other programs can slow down your computer and cause it to use more resources than necessary when they are running at the same time as Tor browser.
Quick Tip:
This is not a problem with the Opera GX Control Panel, which displays the CPU and RAM utilization of a specific opened tab or multiple tabs.
It also allows restrictions over the resources that the Opera GX browser will use, and it will keep to those limits until you further change them.

What can I do if Tor browser is using too many resources?
1. Disable Javascript
It’s not uncommon for the Tor browser to use 100% CPU on computers with older processors and/or limited RAM. This can cause the computer to run very slowly and even crash.
2. Disable HTTPS Everywhere
Tor Browser also has built-in HTTPS Everywhere, which automatically makes secure connections whenever possible. This can make your Tor browser use high CPU while browsing or during startup. Once disabled, you should see significant changes.
3. Install NoScript
NoScript blocks JavaScript and Flash elements on websites that you visit. This will prevent the Tor browser from using high CPU usage while idle.
Hopefully, you have been able to bypass the high CPU usage in your Tor browser with the solutions outlined above.
