How to know if my addons will be compatible with the newest version of firefox before updating? I don't want to update first and then have half my addons not work. I have FF 56.0.2 the version just before quantum rendered 90% of my addons useless which is why I downgraded.

I need to know if I can check compatibility before updating. I have a lot of addons.

hi, addons incompatible with firefox quantum will be labelled as "legacy extensions" when you take a look in the addons manager.
