I just upgraded to Firefox 57 Quantum. None of my favourite extensions are compatible or will be. I am really unhappy, as it makes it impossible for me to use my workflow on FF.
Btw, my two best faves are ProfileSwitcher and MakeLink.

@Michel Don’t tell me Apple took over the upgrade process for Fire Fox

A work-around for a few months is to switch over to the Firefox Extended Support Release release, which still has the pre-quantum machinery https://www.mozilla.org/en-US/firefox/organizations/all/
Beyond that, the choices seemingly are to cave in and lose the add-ons you currently use, or to switch over to one of the pre-quantum firefox forks that will continue to support the old-style add-ons, for example PaleMoon https://www.palemoon.org/ or SeaMonkey https://www.seamonkey-project.org/
I haven’t updated to v57 yet (waiting for the compatible NoScript release) but I will try it and see how it goes. I do lament their policy decision that add-ons should only be able to modify the contents of a web page, not the behavior of the browser itself. They justify this restriction as a prerequisite for significantly improved security and performance. I’m thinking they have broken the main reason we chose Firefox over alternative browsers.

I totally agree with you. I was a very early Firefox adopter: I believed (and believe) in opensource as an ideology. I don’t feel good about becoming an exclusive Chrome user 
I like the upgrade so far because Firefox seems to need a lot less memory than before. I am one of those people who have a habit of using way too many tabs simultaneously, which takes a lot of memory and in the end causes Firefox to stop responding. Usually when I looked at the memory usage in task manager, Firefox would be at 1200-1900 MB. For the sake of testing memory usage, I’ve just opened 41 tabs and it seems to hover between 220 and 295 MB. I think that’s a major improvement

@Michel you could always go with one of the Chromium (opensource) forks that respects your privacy such as Iridium Browser.
