I have been a user of Opera browser since 4 years now. After having tried Safari, Firefox and Chrome, Opera was the browser which worked well, consumed less memory on my machine and looked really good. Their video pop out utility built right into the browser is one of my favourite features.
Mozilla recently announced the public release of their latest version of Firefox. If you are yet to give it a try, please do. It is so much better than before.
Software rewrites are hard. There are so many things you could mess up when, but that does not seem to be the case here. Quantum looks really good, is really fast and consumes less memory on my machine than all the other browsers. Also, the new developer tools are super helpful.
Congrats to everyone who worked on this release 🎉
