Not what it used to be 1 stars by asrs2007 Aug 10, 2016 (Read all my 6 reviews)
It used to be my favorite, but after it refused to work with java, I had to give it up and was surprised to see that new generation brosers were better in many respects. show Review details
Good, but with exceptions. literally. 3 stars by kpupright799 Jun 18, 2016 (Read all my 3 reviews)
Once upon a time, google was simple, fast, and excellent. Now it is huge and invasive. Firefox seems to have followed the same path. As always since I first started using it, Firefox has had excellent design and interface. The problem has come since the early 30s versions and the browser getting more and more bloated. Resource use in this last build is astounding, and I'd love to send the plugin container to another planet, set fire to it and bury its ashes. Constant "breakpoint" errors leading to crashes prompted repeated clean installations trying to gain stability to no avail. Getting a system crash and good ole blue screen was the final straw. Haven't seen that since Bugle was a pup and have no desire to deal with it for the sake of just trying to look at the internet. It may work for others but for now I've had my fill. The search continues. show Review details
Still a great browser 5 stars by LowStrung Jan 24, 2016 (Read all my 14 reviews)
User customizations, which have always made Firefox so flexible, are still possible. Also, I'm seeing great performance as far as speed is concerned, and stability as well. The memory leaks I found in an earlier version haven't shown up in 43.0.4. So far I haven't encountered any difficulties in handling the sites I visit regularly. Some of the UI changes are a bit disconcerting. The first thing I noticed was that the buttons on the bookmarks toolbar were displayed at the very bottom of the toolbar, which had a very large top margin, but I eventually fixed that by editing userChrome.css, which has always helped me tweak the UI in the past. Some extensions may cause Firefox to start up a bit more slowly, particularly Adblock Plus. At any rate, although I previously felt satisfied with my very old version of Firefox and was refusing to upgrade it, I'm glad I eventually gave in and installed 43.0.4! show Review details
