So far less than impressed with FF 57.0 Quantum on this win10 system (much prefer my Firefox 52.4.0 ESR on XP), don’t like the layout and lack of configuration at all. Now we have the long wait for add-ons, not just NoScript 10.0, I currently have 6 add-ons compatible and 26 legacy add-ons awaiting update if that ever happens.
If I had wanted this kind of hassle I might as well have changed browsers. I don’t think I will be alone on this regard.
It is still supported for Firefox users on the ESR version, as are the Legacy Add-ons, so it is still beneficial for them. Personally I’m not very happy about Firefox Quantum, look, layout, lack of configuration, add-on support, all of the things that made firefox popular to start with.
