Firefox&#x27;s problem is not lack of features. It&#x27;s performance.<p>To be sure, Firefox isn&#x27;t the worst by many metrics, but it&#x27;s no longer the stand-out that it was circa 2005-2008. That&#x27;s why Firefox users left it for Chrome.<p>And here we are in 2016, I feel that Firefox has a legitimate chance of fighting back if they get their act together. Chrome has become heavy on resource usage while Safari can be sluggish at times. Microsoft has done a great job with Edge but it&#x27;s bound to Windows 10. This is the opportunity that Firefox should seize.<p>Yet, they seem to be permanently confused about what they want to do. Chucking Firefox OS was a brave and laudable choice (I say this as a former user, not just an owner, of Firefox OS). But then they work on this? Seriously? Just keep your heads down and concentrate your resources on making Firefox faster and more efficient. Everything else will come with it.
