The problem is Firefox has a bunch of redundant and old component, for example there are three history components, one in library with crlt + shift + h, one in side bar with clrt + h, one in firefox view; two bookmark view, one in side bar and one in library, etc. The library is old and sluggish, too many component on it, the side bar is too small, ....
I think Firefox should be reordered the functionalities and key bindings. Beside that we should make the UI for it better so people will have enough functionality they need, I personally refer functional to be appeared in a new tab which will large enough to view and tailor. Please keep the browser clean and easy to use if you want to attract people to migrate from Chrome. Many people complain about Firefox UI and its workflows which prevent them from stop using Chrome.
