I don't get a lot of the negative sentiment here. To me Firefox is vastly superior to Chrome. Mozilla refactored and optimized performance years ago, which fixed many issues I had back then. It's open source, not driven by the interest of gathering data for the purpose of selling ads. I've set it up in exactly the way I like with some extensions and customizations that aren't possible in the Google browser. I can have hundreds and hundreds of tabs open without my computer grinding down to a halt. Is it perfect and aren't there things that can be improved? No. But it's pretty near to me.
