It’s not a fault with the browser and more a requirement of the web app that isn’t being met. Chrome may be struggling to run smoothly because it needs more CPU power. If you’re using a particularly complex web app, it’s worth freeing up system resources. If you’re using Chrome and it often enters an unresponsive state, there is likely a problem with the browser. The browser will use more RAM if you’re using a web app like Pixlr but it will still work. The browser is still powerful and often the ideal browser for using powerful web apps. Its memory leaks are rare but it will use up quite a bit of RAM. Google Chrome consumes quite a bit of RAM. Chrome still has a clean UI but it has since grown to consume more system resources. It’s low resource consumption, and its clean UI was what led it to dominate the browser market. There was a time when the browser was one of the least resource hungry browsers on the market.
Google Chrome is the most popular browser.
