This is my experience with Firefox, there will be no sources provided. I remember using Firefox since I was in college in 2004 and I can tell you what happened when I first tried Firefox 4. The performance was horrible for a very simple reason: the system requirements were increased _tenfold_ and it was pretty much impossible to enjoy browsing using it on older hardware. Extensions started breaking and the menu options would suddenly change place, function or disappear altogether without any prior warning or explanation. Meanwhile, Mozilla devs would either ignore the feedback or post snickering comments on their blogs. The constant version change made it so things were rapidly falling apart - you could no longer rely on Firefox to stay one and the same for any period of time. I saw that Firefox was going downhill, but it was still far superior to all browsers simply due to the wealth of extensions it had. And now, what is the most recent change to Firefox paradigm? Locking the extension ecosystem inside a walled garden. I currently use Palemoon and I look forward to Edge, which promises a basically open-source environment, which will include extensions. Now that´s irony.
