Switched from Chrome to Firefox, and my CPU usage literally dropped from 80% to less than 10%. How is this possible?

Chrome has a nasty reputation for being a resource hog. It eats up RAM,it spikes in CPU usage and as a result, it kills battery life on portable devices. To be fair, Firefox is no saint either when it comes to resource usage, but compared to Chrome it’s definitely more mindful and less greedy.Google Chrome is just so slow and annoying. Right? Google is now rolling out major changes to the browser that fix memory problems and actively discards unused tabs.

The downsides are that Firefox has slower startup times (because Chrome is constantly on in the background) and slower page loading speeds (because it doesn’t steal CPU cycles like Chrome).

One other resource-related point to note is that Firefox supports lazy tab loading, which means that when you open new tabs, they won’t start loading until you select them. This prevents your computer from bogging down when you open several tabs at once.

Completely makes sense. I tried to see what chrome is doing behind the scene and it seems to be spawning many helper processes that eat great resources. Another reason could be that my chrome has a few extensions and those are using CPU. @barudwale20

Corrupted installation is my best guess
