The Desktop version is far better than the Android one. Too slow, takes a lot of time. Please fix this.

To be fair, the desktop one is difficult to carry in your pocket. We do try to make Firefox for Android as fast as possible, but we also want to make sure that it is small enough to be used by many people on many devices all over the world.
I recommend that you give Firefox Preview a try. It is built a little bit differently and I have found that it is faster and easier to use.
