The new firefox quantum is very bad. I'm angry and tired of browsers that do what they want and not what I want. This quantum firefox disabled 4 extensions that are indispensable for me: sage, download status bar, password exporter, and saved password editor. I format my pc every month because internet is full of worms (and antivirus can do nothing against them). For me it is indispensable to export password and bookmarks (and I donìt want to keep them online, where they are not secure). The version 52 of firefox was ok, and I did'n want to upgrade to this awful and impratical new version. But he did the upgrade automatically. Why do they put this option of automatic upgrade by default? This is an harassment to users. I'm so angry and tired of microsoft, and now firefox is becoming the same: a system that do what he wants, that spies you, that installs things that you don't need, and that have many boring options that I don't like. I don't need the library for instance, and the download section is too slow to reach (I prefer download status bar). Moreover, the new icons in black and white, are awful. I don't understand why you change things that worked well as trhey where before. You have to change only things that are wrong, not the one that are good. This new version of Firefox is making me sick. Thank you.
