I think Firefox instead of concentrating more on their browsers; they started to concentrate on their Smartphone OS. Now not only Firefox mobile version but also the desktop version is not good. The startup of Firefox desktop has been improved but they are still very slow when opening pages. Sometimes when the webpage contains lot of animations, they fail to open the page or the animations are not functioning properly. I think the popularity of Android and Chrome made them to create Smartphone OS. I hope they won’t fail in the Smartphone platform.
