The web browser is arguably the most important piece of software on your computer. You spend much of your time online inside a browser: When you search, chat, email, shop, bank, read the news, and watch videos online, you often do all this using a browser.
I’m experimenting with the Google “Chrome” browser. It is a LOT faster than Firefox and has much less hit on the CPU. Firefox has come to be a resource hog and crashes frequently. I’ll likely go back to it when they get over the current issues, but right now Chrome is kinda interesting.
