    I want to talk about this early version of a browser. It's missing some things, but tech-wise, it's really good! It runs super fast on my phone and doesn't mess up webpages. The address bar at the bottom is a nice touch after I got used to it. A few small gripes, especially with tabs - the close tab button is tiny, and going back sometimes takes me to the tab list instead of the previous page.

    Oh, I've been using Firefox Preview and it's really speedy. The collections feature is a lifesaver – no more endless search for bookmarks! It's quicker than the regular Firefox browser. Pages load up instantly. Initially, I didn't like the bottom address bar, but with my new Galaxy S10, it's handy on a bigger screen. Everything feels smooth and I haven't found any faults yet.

    I tried the nightly version after enjoying the regular release and it's working great! I really appreciate its speed and stability, outshining Chrome and other browsers. Even though I prefer to use Nightly, I stick with Firefox ESR on my Windows 7 computer. My only plea to Mozilla is to not drop support for Windows 7. Keep up the excellent work, Mozilla!
