The screenshot was taken after completely clearing the browsing data and I have 0 extensions installed. Second of all, after removing all of my extensions and clearing all of my browsing data, nothing changed. First of all, I have never used Grammarly. I found this thread, which suggested that some extension was causing this problem, but that is not the case. Brave is at 300% CPU usage with one tab open. Firefox was usually around 2% CPU usage with 20 tabs open. In the screenshot, you also see Firefox at 4% CPU usage - note that both Brave and Firefox are idle in the screenshot.
