I really like the Firefox browser. It has one serious flaw, however: stability. After using it for a lengthy period with lots of tabs open, it will eventually crash. I have seen this many times. Other than that, it's a really great browser, and has terrific recovery after a crash. As for the new Edge browser, I have found it to be less stable than Firefox thus far, but also less capable than both IE and Firefox in one key area of functionality upon which I rely: the Edge browser offers no way to create a Windows shortcut to a web page that is currently being viewed. IE allows one to right-click the page and select Create Shortcut, whereas Firefox offers the Deskcut plugin for a similar, though somewhat less polished (i.e., more manual) capability. No such functionality or plugin is exposed or exists right now for the Edge browser, and for me, that alone is enough to cause me not to use it much. Chrome is also great, but like the Edge browser, it too offers no way to create a desktop shortcut to a web page being viewed, so far as I know.
