I have been using FF exclusively since its infancy, so I am not just a FF newbie.....but a real long time user. Heck, I go back all the way to FF3 in 2008, almost 10 years ago. I also came to rely on the many add-ons that became available over the years. When FF57 installed itself on my computers, I about panicked. Not only because it looked so different, but because 90% of my add-ons broke. I was pissed at first and started to explore MS Edge and Google Chrome, both of which are fine browsers with available add-ons that closely matched what I was used to with FF. But then I thought to myself, shoot....I've been using FF for so long that I couldn't imagine myself using any other internet browser. So, after the initial shock of doing without some of my long time favorite add-ons, I went in search for some replacements and thankfully found some that replaced the ones I had lost. I also was happy to see that some of the others I was used to had been updated, and I hadn't lost them after all. I am happy to say, that I am back to pretty much the FF I have been used to for so long now. It was a transition for me, but not nearly as tough as some people are making it out to be on this forum. There is still a healthy community of developers creating FF add-ons, and I am sure if people would just be patient, Mozilla will not let them down. Been using Windows PC's since the old IBM 8086 and Win 3.1 and have seen a lot of software programs have their ups and downs. Some continue to develop better software, and some eventually die. I believe Mozilla is trying to do the right thing and will continue to give us a browser that not only performs better, but gives us a safer internet browsing experience. Unfortunately, they will not be able to please everyone, but hey....fortunately for those that just can't deal with the new FF, the market is chock full of all different flavors of browsers.
