Firefox uses a lot of CPU power.
Firefox uses a lot of CPU power.
Hello everyone! It looks like Firefox is putting a lot of strain on your CPU, even though there are multiple tabs open and Opera is running too. (Your laptop is a Dell XPS 12 with 4 GB RAM and an i5 4200U.) Have you tried checking the system resources or closing unnecessary applications? Also, consider updating your browser or checking for any background processes that might be consuming resources.
It's using HTML5 (Firefox can't run Flash). Trying AdBlock didn't change this.
